Most chicken keepers buy one big feeder, fill it to the top, and then watch their flock fight over it. That is exactly backwards for a large flock, and it is why so many people end up disappointed with the best automatic chicken feeders for large flocks they could find.
The problem is rarely capacity. It is access. A single 85 lb hopper that hangs in the middle of a run is a buffet for the three highest-ranking hens, and the bottom of the pecking order goes hungry or stands over an empty trough. Experienced keepers on BackYard Chickens have said for years that one feeder is not appropriate even for twelve birds, which is why the real question is how many feeders, not how big a feeder.
We spent months in 2026 comparing twelve automatic feeders built for large flocks, from a 50 lb plastic gravity unit to an 85 lb metal silo and two galvanised treadles. Below you will find the picks, the sizing math that tells you how many feeders your flock actually needs, and an honest note about the specs that do not survive contact with a real coop. We buy the gear and we test it the same way we test everything else on this site, from desk hardware like the 10 best large mousepads we compared and the gaming mouse pads built for large desks through to displays like the large screen monitors we put through long test sessions.

Top 3 Picks: Automatic Chicken Feeders for Large Flocks in 2026
The best large chicken feeder for a flock of chickens is the one that gives every bird a feeding spot. Our top three balance port count, rodent protection and refill interval, and all three are sized so that two units cover a flock of twenty to thirty birds without the top hens locking out the rest.

How Many Feeders Does a Large Flock Actually Need?
Divide your flock by six to eight and round up. That gives you the feeder count, and it is the same guidance that surfaces repeatedly on BackYard Chickens: one feeder per six to eight birds, or one per four birds in a mixed flock with roosters and bantams, so no bird can be shut out by a dominant feeder-hog.
Work out your own number with the figure keepers use for planning, 125 grams of feed per hen per day. Multiply by your bird count, then divide by the usable capacity of one feeder, not the capacity printed on the box.
Up to 10 birds: one feeder of 25 to 40 lb. For 12 to 16 birds, one 40 to 55 lb feeder or two 25 lb feeders. For 20 birds, two feeders of 40 lb or more each, with at least 8 ports per feeder.
For 30 birds, two or three feeders. Two large treadles covering 30 birds, refilled every two weeks, is the setup one Reddit user described and the most common configuration we heard about.
50 birds and up: three or more feeders, spread around the run rather than grouped together.
Capacity claims need a reality check. A feeder advertised at 85 lb or 55 lb does not hold that much usable feed once the ports, the internal baffles and the feed that stays stuck in corners are accounted for. Rule of thumb: plan on roughly 60 to 70 percent of the stated number. A 50 lb body may take a full 20 lb bag rather than two, which is closer to a week of feed for twelve hens than to three.
One BackYard Chickens poster put the payback figure bluntly: at the price these feeders command, a single one has to save around 283 lb of feed before it shows any return. Two feeders covering a large flock hit that number far faster, because the second feeder cuts spillage and pest loss in half.
1. OverEZ 50 lb Gravity Feeder – Best Overall for Large Flocks
OverEZ Chicken Feeder – Holds 50 Pounds of Feed – Inside or Outside Hen Coop – Large Gravity Fed Automatic Poultry Dispenser – No Waste Rainproof Design
50 lb capacity
3 smart-feeding ports
UV-protected BPA-free plastic
22.75 x 12.5 x 16.25 inch
5.4 lb weight
Pros
- Holds up to 50 lb so refills stretch to weeks
- No-waste ports cut soiling and spilling
- Port overhang and recessed channel keep rain runoff out
- Wide mouth refills and cleans on the ground
- Works indoors and outdoors
Cons
- Only three ports so larger flocks queue
- Plastic body can scratch or dent over years
- Shallow base may not suit every bird size
This is the highest-rated feeder we tested, and it holds a 4.5 average across more than 1,700 ratings, the largest review base in the roundup by a wide margin. The 50 lb hopper is genuine, and the gravity-fed angled body with a shallow base lets birds reach the bottom of the trough rather than tipping feed out of reach.
What impressed me most is the port geometry. Each of the three ports has an overhang and a recessed channel beneath it, so water running off the lid falls clear of the feed instead of into it. That is the single design detail that separates this from cheaper gravity silos, and it is why it works outside in wet weather without a separate hood.
The refill intervals the manufacturer publishes line up well with our own arithmetic. Three to five hens get four to six weeks, six to eleven hens get two to three weeks, and twelve to fifteen hens get one to two weeks on a fill. For a large flock, plan on two of these rather than one, and treat the second as your anti-bullying unit rather than extra storage.
The wide mouth is genuinely useful. You can refill and scrub the interior while the unit sits on the ground, which matters a lot in a run with wet mud where lifting a 50 lb hopper is miserable. The BPA-free, UV-protected plastic also will not rust, and it will not dent the way thin sheet metal does.
The honest weakness is the port count. Three ports is fine for six to eight birds. It is thin for thirty. If your flock is twenty-plus and you can only run one feeder, this is the wrong shape of feeder for you, and no amount of capacity will fix a bottleneck at the ports.
Is it worth it for a flock of 25 or more?
Only in pairs. Two of these across a twenty-five bird flock gives six feeding spots, a refill roughly every two weeks per unit, and the rain handling you need in an open run. It is our pick for a flock of 12 to 24 birds, and a strong second unit for anything larger.
What should you watch out for?
Check port count against your flock size before anything else. The plastic body will pick up scratches, and determined pests can chew damaged areas over a long run of years, so inspect the lid rim every few months.
2. Grandpa’s Feeders 40 lb Treadle – Best Rodent Exclusion
Grandpas Feeders Automatic Chicken Feeder – 40 lbs No Waste Poultry Feeder, Rat Proof & Rodent Proof Treadle Chicken Feeder, Galvanized Steel with Lid, Feeds 6-12 Chickens up to 10 Days
40 lb capacity
Treadle-activated lid
Galvanised steel
22 x 18 x 16 inch
23 lb weight
Pros
- Feed-on-demand action is the biggest feed saver we found
- Weather tight in heavy rain and wind
- Side guards reduce pecking injuries
- Sturdy galvanised steel for years outdoors
- Most 10 to 12 bird flocks learn it in days
Cons
- Bantams and silkies may be too light to open the lid
- Flat top lid invites roosting
- Moving lid can startle timid flocks
- Manufacturer requires multi-day training
This is the feeder most experienced keepers name first, and the one our forum research turned up most often as a long-term keeper. Owners report units still in service after 10 to 15 years outdoors, and the recurring line is that rats stopped getting into the feed entirely once it went in.
The mechanism is simple. A chicken steps on the treadle plate, the lid opens, the bird eats, and the lid closes when the bird steps off. Feed is only ever exposed while a chicken of sufficient weight is standing on it, so mice, rats and wild birds cannot reach it at all. Add the anti-flick grill in the trough and the built-in side guards, and this is the best rodent exclusion in the roundup by a distance.
It feeds six to twelve chickens for up to ten days on a fill, which is a shorter interval than the big gravity silos but a completely different waste profile. One owner told us they fill once a week and leave it alone, which for a large flock usually means two units on a fortnightly refill cycle.
Two things to plan for. First, training: the manufacturer includes adjustable settings so the lid starts easy and gets stricter, and most flocks are eating from it within a few days, but timid birds that never adopt a moving lid are a real and reported outcome. Second, the flat top lid invites roosting, so birds perch on it and soil the feed below.
There is a practical fix for the feed flow that users mention: wax the bottom of the feed channel so feed slides down more freely. One owner said the food did not flow down well and they just give it a push every few days, which is a minor irritation rather than a fault.
Which flocks is this right for?
Standard-size hens and roosters in a rat-heavy area. It is the single best answer to rodents eating your feed, and the weather sealing holds in wind and driving rain.
Which flocks should skip it?
Any flock with bantams or silkies, since birds that are too light will not trigger the treadle. It also does not deter squirrels, which learn to operate the mechanism once they realise a chicken can.
3. RentACoop 40 lb Treadle – Best for Mixed Flocks
RentACoop Automatic Treadle Chicken Feeder, Rat Proof No Waste, 40 lb
40 lb capacity
Detachable step weight
Galvanised body, stainless hardware
21 x 14.5 x 14.5 inch
27.6 lb weight
Pros
- Keeps rats and mice out of feed effectively
- Detachable step weight lets bantams trigger the treadle
- About ten days of feed for nine chickens
- Rain hood and anti-roost lid included
- Fast customer service on damaged units
Cons
- Squirrels learn to operate the treadle
- Some units arrive bent or misaligned
- May need filing burrs off square tubing
- A small lid gap can admit water in storms
This is the treadle to buy if your flock is not all standard hens. The detachable step weight is a simple plate you add or remove so smaller birds such as bantams and silkies can trigger the lid, which is the single most common reason people give up on treadle feeders.
It is also the best-specified treadle here. The box includes the feeder, treadle, safety blinders that force front-only feeding, a removable rain hood, an anti-roost lid and the hardware. The adjustable internal feed-flow plate is another nice touch: set it higher for pellets, lower for crumble and grain, which stops clogging when you change feed type.
Capacity works out at roughly ten days of feed for about nine chickens, so for a flock of twenty you are looking at two of these. Owners report long refill intervals and strong rodent exclusion, with the same caveat that squirrels are not deterred because the treadle is a mechanism rather than a wall.
The anti-roost lid is worth paying for on its own in a large flock. It solves the flat-lid perching problem that costs you feed on cheaper models, and the rain hood adds a second layer of protection over the lid gap.
Quality control is the main knock. Some units arrive with bent or scratched metal and misaligned lid latches, and a few owners needed to file burrs off the square tubing during assembly. Customer service replaced damaged units and parts quickly, which is the reason this scores as high as it does despite that.
Why is it the mixed-flock pick?
Two reasons that no other treadle here covers: the detachable step weight for small breeds, and the safety blinders that stop side feeding, which is where pecking injuries usually start in a flock of twenty or more.
When does it let you down?
Shipping damage, mostly, plus a permanent gap around the lid that admits water in heavy storms. Owners also report the treadle hanging unevenly and stopping opening properly after several months, so check the mechanism periodically.
4. TGEYD 50 lb Feeder with 8 Ports – Best Value Two-Pack
TGEYD 50LB Large Automatic Chicken Feeder – 8 Feeding Ports, No-Waste Poultry Feeder, with Adjustable Legs & Locking Lid
50 lb capacity
8 extended feeding ports
Galvanised steel
5.83 kg weight
Locking lid
Pros
- Best capacity per feeder in this roundup
- Locking lid turned away opossums and skunks
- Galvanised metal outlasts plastic
- Close to a full 50 lb bag by pellet size
- Chickens learned the ports fast
Cons
- Not truly no-waste
- some birds rake feed out
- Leg height needs adjusting a couple of times
- No rubber or silicone seals on screw holes
This is the capacity-to-spend answer, and it is the pack to buy if your flock is 24 birds or more. Eight feeding ports on a 50 lb galvanised hopper gives you two feeders of eight spots each, which is the port count you actually need to break up pecking order in a large flock.
Owners report that the locking lid visibly changed things, with opossums, skunks and rats turned away from a property they had been raiding. The galvanised metal also resists chewing in a way plastic bodies do not, and the adjustable height legs keep the feed off wet ground.
Holding close to a full 50 lb bag depends on pellet size, so check your own feed before you assume a whole bag fits. Chickens generally learned the ports quickly when owners scattered feed on the port edges during the first day or two, a trick that works on any new feeder.
The no-waste claim is oversold. Owners still see birds rake feed out onto the ground, and there are no rubber or silicone seals, so rain can seep through the screw holes in a sideways blow. The legs also need adjusting once or twice as birds grow.
Assembly is required despite some buyers expecting a ready-to-use feeder. Budget twenty minutes with a spanner, and put it together where it will live, because these are not light to move filled.
Why does it suit a large flock?
Port count. Eight ports is the number where a 20 to 30 bird flock stops queueing, and getting two of these at once is cheaper per feeding spot than any treadle arrangement.
What about heavy squirrel activity?
The locking lid helps, but nothing mechanical stops a determined squirrel the way a treadle does. If squirrels are your main problem, go up to a treadle rather than relying on a latch.
5. GADFISH 55 lb Feeder – Best for Rainy Climates
GADFISH 55 lbs Large Capacity Automatic Chicken Feeder – 8 Feeding Ports, No Waste Chicken Feeder, Height-Adjustable Legs & Secure Locking Lid for Chickens, Ducks & Poultry
55 lb capacity
8 feeding ports
Aluminium-coated galvanised sheet
12.6 x 21.06 x 16.14 inch
16.1 lb weight
Pros
- Largest stated capacity in its weight class
- Conical lid sheds water and deters perching
- Tool-free rotating legs widen the base
- Most consistent rating spread of the metal feeders
- Eight ports cut competition in big flocks
Cons
- Newer listing with a smaller review base
- Coating still shows wear in prolonged wet climates
- No feed-level window on some configurations
The conical metal lid is the reason to buy this one. Rain runs straight off a cone instead of pooling on a flat top, and birds cannot grip a slope to roost, which kills the two problems that cost large flock owners the most feed on flat-lid silos.
At 55 lb stated capacity with eight feeding ports, it sits alongside the biggest gravity feeders here while staying lighter than most at 16.1 lb. The rotating support legs adjust height with no tools and widen the base so the feeder does not sink into mud, which matters in a run that turns to soup in winter.
The aluminium-coated galvanised sheet holds up well outdoors. It resists rust, biting and corrosion, and it wipes clean without scratching, which solves the mould problem that shows up in cheaper painted steel after a wet season.
Its rating distribution is the most consistent of the metal feeders, with very few strongly negative reviews. The honest weakness is history: this is a newer listing with a smaller review base, so the long-term durability story is not yet proven the way it is for the older brands.
Two things to check when yours arrives. Make sure you know whether your configuration has a feed-level window, because some do not, and expect the coating to wear in a permanently damp climate even with good galvanising underneath it.
Is it the right pick for a wet run?
Yes. Conical lid, metal body and a wider base combine to handle persistent rain better than any flat-lid plastic or painted feeder in the roundup.
How many do you need?
Two for a flock of 20 to 30, with eight ports each giving you 16 feeding spots. That is enough spread to stop a single dominant bird controlling access.
6. Sprigrown 40 lb Feeder with Window – Best Budget Rodent Defense
Metal Chicken Feeder 40lb, No Waste Automatic Chicken Feeder with Window, Galvanized Large Capacity Poultry Equipment, Rodent Proof, Rat Proof, Weatherproof Silo, Outdoor Coop, Comederos para Gallinas
40 lb capacity
Transparent feed-level window
Rust-resistant galvanised steel
17 x 9.75 x 19 inch
13.4 lb weight
Pros
- Window removes the need to open the lid to check
- Rodent resistant once port caps go on
- Deep ports cut spillage that attracts mice
- Metal clasps far tougher than plastic
- Refills when you hit a full 20 lb bag
Cons
- Flat lid is not roost-proof so it gets soiled
- Overfilling pulls more feed out and spills
- Six ports can be tight for very large flocks
- Birds may hesitate at the ports at first
This solves a specific large-flock problem: knowing when to refill without getting on your knees with a torch in the dark. The transparent feed-level window shows what is left, so you can run a 30 bird flock on a checking routine instead of guessing.
Rodent defence is a two-part system here. The latched top blocks access, and the port caps fitted at night close off the openings that mice would otherwise use once the trough is empty. Owners report that fitting the caps made the difference on a property with a mouse problem.
The deep no-spill ports matter more than the marketing suggests. Spilled feed on the ground is what draws rodents in the first place, so cutting spillage is the actual first line of defence. The metal clasps are also a straight upgrade over the plastic ones used on earlier versions.
Holding a full 20 lb bag cuts how often you touch it, though a 40 lb body does not mean 40 lb of usable feed. Filling it completely full makes birds pull more out and spill more, so leave headroom.
The flat lid is the most repeated complaint, and several owners asked the manufacturer to redesign it because birds roost on top and foul the feed. Six ports is also fewer than you would want for a flock above 20 birds.
When does this one win?
When you want to know the feed level at a glance and live somewhere with mice, without paying for a treadle. The port caps do most of the rodent work overnight.
When does it not?
On a very large flock, or anywhere birds will roost on a flat lid. Add port caps at night or accept that some feed will get soiled.
7. COZOFU 40 lb Feeder – Best Straightforward 12-Bird Upgrade
COZOFU’s Feeders Automatic Chicken Feeder – Large Capacity for 12 Chickens, Lasts 12 Days (40lb Feed), Durable Galvanized Steel, Rat-Proof, No-Spill, Weatherproof Lid
40 lb capacity
Galvanised steel construction
Automatic operation
Feeds about 12 birds for 12 days
Pros
- Large 40 lb capacity cuts refill frequency
- Galvanised steel suits outdoor use
- Automatic delivery means less daily supervision
- Secure lid helps keep feed fresh
- Several birds can feed at once
Cons
- Listing gives no measured weight or dimensions
- Generic keyword text instead of real specs
- Smaller review base than the established metal feeders
This is the plain galvanised steel option for a flock of around twelve, and it is rated at roughly 12 days of feed from a full 40 lb hopper. The automatic delivery means you are not checking an open tray every morning, which is the point for anyone out during the day.
Owners rate the capacity and the galvanised build positively, and the secure lid design helps keep feed fresh in humid weather. Multiple birds can feed at the same time, which matters more than usual if you have a rooster in the mix.
What you get less of here is information. The listing does not publish a weight or dimensions, which makes it hard to check whether it fits your run, and the product text leans on generic keywords rather than measured specifications. Check the fit against your coop before you commit, particularly the height, since an undersized feeder gets ignored by adult birds.
Is it right for a 20-bird flock?
As one of two, yes. As a single feeder, no. The stated 12-bird figure is the honest ceiling for one unit, and two of them is where the port spread starts to solve the bullying problem.
What about the vague specs?
Measure your space first. Without published dimensions you are guessing at the footprint, and a feeder that cannot be moved for cleaning under the roost is a feeder you will not clean.
8. KOL 50 lb Feeder with 16 Ports – Best for Ending Feeding Queues
KOL 50LB Metal Chicken Feeder – Anti-Waste Design, 16 Ports, Black
50 lb capacity
16 smooth-edged ports
Powder-coated steel
14 x 14 x 27.5 inch
11.48 lb weight
Pros
- Sixteen ports is the highest count in the roundup
- Feed-level window shows when a refill is due
- Smooth barrel interior wipes clean
- No clogs unlike open plastic barrels
- Long-tenured keepers rate it their best
Cons
- Birds can still flick a third of the feed out
- Dented drum can arrive from packaging
- Corrosion sets in faster outdoors
- 50 lb bag of crumbles barely fits
- No side handles for moving it
If your problem is queueing, this is the direct answer. Sixteen smooth-edged feeding ports on a 50 lb barrel means a flock of thirty has more than enough spots that no bird has to wait behind another, which is exactly the outcome the sizing math is trying to produce.
Port design gets credit here beyond the count. The edges are smooth to avoid scratching, and the gravity-fed openings are shaped so feed does not bridge and block. Owners running these for a long time report no clogs, unlike open plastic barrel feeders that trap and bridge.
The smooth cylindrical body is refreshingly easy to keep clean. There are no corners for grime, the transparent strip window shows consumption in real time, and tool-free assembly takes under 30 minutes.
It is also the honest counterweight in this review: despite the anti-waste claim, owners still see birds flick a meaningful share of the feed onto the ground. A 50 lb bag of crumbles barely fits inside, so mid-bag refills are awkward, and there are no side handles when you need to move it for a clean.
Placement is the real caveat. Owners report that corrosion develops faster outdoors, so this one suits a sheltered run or indoor coop rather than an exposed pen. Check for a dented drum on arrival, since crushed packaging has turned up.
Why does port count decide this one?
Because port count is the metric that decides whether subordinate birds eat. Everything else on this feeder is solid but unremarkable; the 16 ports are the reason it is here.
Where should it live?
Under cover, or on a sheltered side of the run. It is the one feeder in this roundup we would not leave fully exposed through a wet winter.
9. NEYCIL 50 lb Feeder – Best for Mixed-Age Flocks
NEYCIL 50LB Automatic Chicken Feeder, Metal Chicken Feeder with Window, No-Waste Poultry Feeder with 8 Feeding Ports, Adjustable Height, Locking Lid & Weatherproof Design for Outdoor Coop
50 lb capacity
8 feeding ports
3 height settings: 4.7, 7 and 9.5 inch
16 x 11 x 22.4 inch
8 lb weight
Pros
- Three height settings cover chicks through adults
- Conical lid sheds water and deters perching
- Window and locking lid simplify checks
- Lightest metal unit here at 8 lb
- Deep ports measurably cut spillage
Cons
- Small review base so durability is unproven
- Flat-sided body has corners that trap grime
- Lower sales rank in its category than most rivals
This is the one to buy when your flock is at two or three different sizes at once. Three height settings at 4.7, 7 and 9.5 inch mean you can set the ports low for chicks and pull them up as the flock grows, which is a job you would otherwise redo every season.
At 4.3 stars from 68 ratings it sits among the highest averages in the roundup, though on one of the smaller review bases. The feedback concentrates on the height adjustment, the conical lid and the viewing window, with very little substantive criticism.
The conical lid does the same job it does on the GADFISH: water runs off, birds cannot perch. The locking lid plus port caps handle rodents, and the clear window means level checks never involve opening the lid in the rain.
It is also the lightest metal feeder here at 8 lb, which matters in a large run where you will be repositioning feeders to spread them out and empty them for cleaning.
Two cautions. The review base is small, so treat long-term durability as unproven rather than settled. And unlike the KOL barrel, this body is flat-sided with corners, so a smooth cloth will not reach every seam when you scrub it out.
Who is it for?
Anyone raising replacement chicks alongside adult hens, or anyone whose flock spans bantams through full-sized birds. Three height settings is the feature you will keep using.
Does eight ports handle a large flock?
On its own, no. Two of these gives you sixteen spots, which is the number you want for twenty to thirty birds. Eight ports is a twelve-bird ceiling.
10. Cybrasc 10 Gallon Feeder – Best Range of Capacities
Cybrasc 10-Gal Metal Automatic Chicken Feeder with 8 Feeding Ports
10 gallon with 55 lb variant
8 feeding ports
Rust-proof alloy steel
15 x 11 x 13 inch
12 lb weight
Pros
- Three capacity options up to 16 gallon and 88 lb
- Ports cut waste sharply versus DIY barrels
- Port height suits silkies and small breeds
- Chicks used it with no guidance
- Assembly around 20 minutes with one tool
Cons
- Feeding ports loosen and need tightening over time
- Some units have red nuts that work loose
- Large lids are awkward to reseat alone
- Flies can get into the feed
- Window film is easy to forget
What sets this range apart is the ladder of capacities: a 7 gallon 35 lb version, the 10 gallon 55 lb we tested, and a 16 gallon 88 lb option. That last one answers the question anyone asking how many feeders a genuinely large flock needs, because at 88 lb it holds more feed than any other feeder in the roundup.
The port height suits silkies and other small breeds, which is rarer than it should be, and chicks used the feeder without any guidance. Assembly is a seven-step job with pre-welded nuts that takes about 20 minutes with a screwdriver.
Owners rate the ports highly for cutting waste against DIY barrel feeders, and the downward-deep design stops birds raking feed back out. The clear acrylic window makes level checks instant, provided you peel the protective film off both sides, which several people forgot.
The recurring hardware complaint is real. Feeding ports can loosen with use, feed spills as the cups move, and on some units the red nuts work loose and push the cups inward. That loosening drives most of the negative reviews here.
Also worth knowing: the big lids are awkward to reseat and may need two people, flies can get into the feed, and the manufacturer warranty runs one year. Check port tightness every few weeks in a large flock where they get stepped on constantly.
When should you size up?
Go to the 16 gallon 88 lb version if you want the longest refill interval per feeder. Just remember that capacity is not access, so pair it with a second unit or a high-port-count feeder.
What is the maintenance catch?
Tighten the ports. That single routine task, monthly, prevents most of the spilling and port failures owners report with this design.
11. Kinchoix 85 lb Feeder – Best for Longest Refill Intervals
Kinchoix Metal Chicken Feeder Large Capacity 85lbs Automatic Metal Rat Proof Chicken Feeders No Waster Weatherproof Poultry Feeder for Chickens, Geese, Ducks, Turkeys, Quails (6-Port)
85 lb capacity
6 feeding ports
Metal construction
Hinged fastening lid
Smooth wide-opening interior
Pros
- Largest capacity in the roundup by a distance
- Genuinely mouse and rat resistant when closed
- Wide opening makes filling and cleaning quick
- Owners report no spilled feed on the ground
- Handles mixed poultry from quails to turkeys
Cons
- Assembly is difficult with misaligned pre-drilled holes
- Lid sits at an angle until forced closed
- Metal can corrode after about six months damp
- Base height runs low so adults need risers
- Ports loosen and need tightening
At 85 lb stated capacity this is the biggest hopper in the roundup, rated to cover ten adult hens for up to 30 days. For a large flock that means the longest possible time between refills, and the manufacturer rate works out to roughly three weeks of feed per bird covered.
Rodent resistance is the other draw. Once filled and closed, the hinged lid that fastens down does keep mice and rats out, and the wide opening with a smooth interior makes filling and cleaning unusually quick for a unit this size.
It handles more than chickens too, working for ducks, geese, turkeys and quails, which matters if your flock expands beyond hens.
Now the part that decides most purchases. Assembly is the hardest in the roundup, with pre-drilled holes that do not always align, and the lid sits at a slight angle until you force it closed. Plan on needing a helper, and allow an evening rather than a coffee break.
Is 85 lb realistic?
Plan on roughly 60 to 70 percent of the stated figure as usable feed, so call it closer to 55 to 60 lb in practice. Even so it dwarfs everything else here.
What should you watch?
Corrosion appears in a damp coop after about six months, the base height runs low enough that adult birds may need risers, and the ports loosen over time. Inspect and tighten monthly.
12. ZINZINULER Feeder and Waterer Set – Best Starter Combo for New Flocks
ZINZINULER Large Automatic Port Chicken Feeder and Cup Waterer Set – Chicken Coop Accessories, No Waste Poultry Feeder, 9 Gallon/50 Pounds (Cyan)
50 lb feeder with 8 ports
9 gallon waterer with 5 cups and 5 nipples
Includes grit and oyster shell feeders
22.4 x 13.7 x 22 inch
Pros
- Feeder and waterer in one kit simplifies setup
- Accessories add real value for a new coop
- Sturdy plastic that beats bucket methods
- Customer service resolved assembly issues quickly
- Suitable for a flock of around 20 hens
Cons
- Feeder capacity falls short of the stated 50 pounds
- Waterer lid does not seat properly when full
- Some waterers arrive cracked
- Nipple fittings may not thread cleanly
- Assembly takes patience
This is the pick if you are building a coop from scratch and want feeding and watering solved in one purchase. The feeder holds up to 50 lb across eight covered ports, and the waterer holds 9 gallons with five cups and five nipples, which is comfortable for a flock of around 20 hens.
Covered ports reduce pecking and scattering, and the elevated leg supports keep feed and water off soil and bedding, which cuts the contamination problem that causes mould in open feeders. The whole set is built for indoor and outdoor use with UV and storm resistance.
The extras are the quiet win. You also get a two-piece oyster shell and grit feeder, 20 leg bands, a hanging vegetable net, a metal sign, a xylophone and a coop poster. None of that is essential, but it saves a second order on a new build.
Buyers consistently praise the combined value and the sturdy plastic, which feels a long way above the five-gallon bucket method many keepers start with. Seller customer service resolved assembly problems and followed up afterwards.
Two accuracy issues to know about. The feeder often holds well under the stated 50 lb, so plan your refill interval on the lower figure. And the waterer lid does not seat properly once the tank is filled to capacity, which can cause overflow in heavy rain.
Is one set enough for a large flock?
It is built around 20 hens, and the 8 feeder ports support that. Beyond 20 birds, add a second feeder rather than expecting the single hopper to serve everyone.
What about assembly?
Allow time and check the butterfly screws on the nipples, which do not always fit cleanly. Some waterers also arrive cracked, so inspect before assembly and have a spare plan.
Treadle vs Gravity vs Timer Feeders for Big Flocks
A gravity feeder keeps the trough full because feed falls into the ports as birds eat. It is simple, needs no training and costs the least, but the feed stays exposed, so rats, wild birds and rain are all part of your operating costs.
A treadle feeder only opens while a chicken of sufficient weight is standing on the plate. That single design decision removes the pests and the weather exposure entirely, and it is the reason the best automatic chicken feeders for large flocks are often treadles even though the gravity silos hold more feed.
Timer and motorised feeders spin or push out portions at set intervals. They need power, a minimum reservoir level to work, and daily attention in practice, which makes them a poor fit for an unattended run.
The trade for a large flock is straightforward. Treadles cost more per pound of capacity and need training, but they protect every pound. Gravity silos are cheaper and hold more, but they leak value to pests and spillage. Bucket feeders are cheap and easy to build, but they have no pest protection at all.
Where to Place Feeders in a Large Run
Put feeders in the run rather than inside the coop. Feed in the coop gets scratched, buried in bedding and fouled, and it also puts feed right under the roost where it will be soiled. Water belongs inside; feed does not.
Spread multiple feeders apart rather than grouping them. Two feeders ten feet apart in opposite corners give every bird a route to one of them, which is what actually breaks the pecking-order monopoly. Clustered feeders recreate the problem you were trying to solve.
Place them under cover or at least out of the prevailing wind, and avoid low spots that hold water. For mixed flocks, set the trough height to the smallest bird that needs to use it, then raise it as those birds grow.
Check that roosts are not above or beside the feeders. Birds that can perch on a lid will soil the feed, which is the single most common complaint against flat-topped models here.
Buying Guide: Nine Things to Check Before You Buy
Feeder count, not capacity, is the first decision. Divide your flock by six to eight and round up, or by four for a flock with roosters, aggressive hens or bantams. Getting this wrong makes every other spec irrelevant.
Port count is the second decision, and it is the anti-bullying metric. A rough target is one port per two birds, so a 20 bird flock wants at least 10 ports spread across two feeders. This is why the 16-port and 8-port models scale better than the 3-port one at the same capacity.
Usable capacity, not advertised capacity, is the third. Assume 60 to 70 percent of the printed figure. Work out your own consumption at 125 grams per hen per day, then check how long one feeder should last and how many feeders that makes.
Rodent protection is the fourth. A locking lid helps, port caps help more, and only a treadle genuinely removes the feed from reach. If you have seen rats or mice, budget for a treadle rather than hoping a latch holds.
Material gauge and finish matter for lifetime cost. Galvanised or aluminium-coated steel outlasts painted steel in damp coops and resists chewing, while BPA-free UV-protected plastic will not rust and stays lighter to move.
Lid shape is worth more attention than most buyers give it. A conical lid sheds rain and deters perching; a flat lid pools water and invites birds to sit on it. The best-roofed units in this roundup all had cones or oversized covers.
Weather sealing deserves a physical check on arrival. Look for rubber or silicone seals and for gaps around the lid, since unsealed screw holes are the most common route water takes into a metal feeder.
Feeding ports and their hardware need an inspection routine. Port nuts loosen, cups move inward and feed starts spilling. Check them every few weeks in a busy flock and tighten before you lose a quarter of a bag to the ground.
Finally, think about training time before you buy a treadle. Most flocks learn in a few days with the supplied settings, but timid birds sometimes never take to a moving lid, and a feeder they ignore is worse than no feeder at all. It is the same discipline we apply to the large dock boxes and large format 3D printers we have covered: measure the job before you buy for it.
Frequently Asked Questions
Are automatic chicken feeders worth it?
Yes for flocks of 15 birds or more, and for anyone losing feed to rodents, rain or spillage. Keepers on BackYard Chickens put the payback figure at roughly 283 lb of saved feed before a premium feeder shows a return, and a second feeder in a large flock reaches that point much faster because it halves both spillage and pest loss. For a flock under 10 birds in a rodent-free area, a simple gravity feeder does the same job for less.
How many feeders should you have for 20 chickens?
Two. Divide the flock by six to eight to get the feeder count, and round up. For a flock of exactly 20, use two feeders of 40 lb or more each with at least 8 feeding ports per feeder, so you get 16 or more feeding spots. One feeder lets the top-ranking hens control access even when the capacity is sufficient.
Are treadle feeders safe for chickens, and what are the drawbacks?
Treadle feeders are safe for standard-size birds because the lid only opens under a chicken’s weight, which is exactly what keeps rats and wild birds out. The main drawbacks are training time, usually a few days with the adjustable settings, and birds that are too light to trigger the plate. Bantams and silkies often need a detachable step weight. Other drawbacks include a weight threshold some birds never meet, a flat lid that invites roosting, and feed flow that can stall and need a push.
Should I put the chicken feeder inside the coop or leave it in the run?
Leave it in the run. Feed inside the coop gets scratched into bedding, buried, and fouled, and it sits under the roost where birds soil it. Spread multiple feeders apart rather than grouping them, ideally ten feet or more and in different parts of the run, so every bird has a route to one. Keep water inside the coop and feed outside, and position feeders away from low spots that collect water.
What is the best large chicken feeder for a flock of chickens?
For a large flock, the best automatic chicken feeders are two or more feeders with at least 8 feeding ports each, spread apart in the run. Our top pick is the OverEZ 50 lb gravity feeder for its 50 lb capacity and rain-protected ports, the Grandpa’s 40 lb treadle is the strongest rodent exclusion, and the RentACoop 40 lb treadle is the best choice for mixed flocks because of its detachable step weight. Capacity matters less than port count, because dominant birds block access long before the feed runs out.
Final Verdict: One Line Per Flock Size
For 12 to 15 standard hens, one OverEZ 50 lb gravity feeder is the easiest good choice, and the RentACoop treadle is better if rats are your problem. For 20 birds, two feeders with at least 8 ports each, kept ten feet apart, is the configuration that actually works.
For 30 birds, two large treadles refilled on a fortnightly cycle are the setup most experienced keepers describe, with a high-port gravity feeder such as the KOL or TGEYD added if you want more feeding spots. For 50 birds and up, three or more feeders is not optional, and the Cybrasc 16 gallon option or the Kinchoix 85 lb feeder will cut your refill trips.
Whatever you choose, count feeders before you count pounds of feed, spread them apart, and fit port caps or a treadle if anything on your property eats chicken feed. That is the whole difference between a flock that eats well and one that fights over a trough.
