How Much Feed Does a Chicken Eat Per Day? Real Numbers
Published: September 7, 2026 · 9 min read
An average adult laying hen eats about 0.25 lb (113 g) of feed per day — roughly half a cup, or 1.75 lb per week. That is the standard figure used by university extension services and it holds up well for common layer breeds like Leghorns, Rhode Island Reds, and ISA Browns fed a 16% layer ration. Heavy dual-purpose breeds run closer to 0.30 lb per day, bantams manage on about 0.10 lb, and fast-growing Cornish Cross broilers can hit 0.35–0.40 lb during peak growth.
But the number on the bag is only a starting point. Weather, breed size, free-range access, and how much feed ends up on the ground instead of in the bird all move the real figure — sometimes by 30% or more. This article breaks down the actual numbers by bird type and life stage, shows the monthly math for real flock sizes, and covers the factors that push consumption up or down. If you want to go beyond per-bird averages, the Chicken Feed Calculator turns your flock size and local bag price into a full daily, monthly, and yearly cost estimate.
Daily Feed Intake by Bird Type
Feed consumption tracks body weight and production purpose. A 4.5 lb Leghorn laying an egg most days burns more energy than a 2 lb bantam pullet, and a broiler built for rapid weight gain out-eats both. The table below reflects widely published extension figures for birds on complete formulated feed:
| Bird Type | Per Day | Per Week | Per Month | In Cups (approx.) |
|---|---|---|---|---|
| Laying hen (light breed) | 0.25 lb (113 g) | 1.75 lb | 7.5 lb | ~½ cup |
| Laying hen (heavy/dual-purpose) | 0.30 lb (136 g) | 2.1 lb | 9.0 lb | ~⅔ cup |
| Pullet (8–20 weeks) | 0.15–0.18 lb | 1.0–1.25 lb | 4.5–5.5 lb | ~⅓ cup |
| Chick (0–8 weeks) | 0.05–0.10 lb | 0.35–0.7 lb | 1.5–3.0 lb | ~2–3 tbsp |
| Broiler, mid-grow (Cornish Cross) | 0.35–0.40 lb | 2.5–2.8 lb | 10.5–12 lb | ~¾ cup |
| Bantam (adult) | 0.10 lb (45 g) | 0.7 lb | 3.0 lb | ~3 tbsp |
One useful sanity check: chickens drink roughly twice as much water by weight as they eat feed. If your six hens are emptying a gallon waterer every two days, a daily feed draw of about 1.5 lb is right on track. When feed consumption suddenly drops while everything else looks normal, check water first — dirty or frozen water suppresses appetite faster than anything else.
Monthly Math for Real Flock Sizes
The per-bird number matters less at the feed store than the bag count. Here is what 0.25 lb per layer per day looks like for common flock sizes, assuming standard layer feed at $16–22 per 50 lb bag (typical 2026 farm-store pricing):
| Flock Size | Feed Per Day | Feed Per Month | 50 lb Bags Per Month | Monthly Cost |
|---|---|---|---|---|
| 3 hens | 0.75 lb | 22.5 lb | 0.45 | $7–10 |
| 6 hens | 1.5 lb | 45 lb | 0.9 | $14–20 |
| 12 hens | 3.0 lb | 90 lb | 1.8 | $29–40 |
| 25 hens | 6.25 lb | 187.5 lb | 3.75 | $60–83 |
What Changes the Number: 6 Factors That Move Feed Intake
1. Cold Weather Increases Intake by 15–25%
Chickens maintain a body temperature around 105–107°F, and when the thermometer drops below freezing they burn extra calories just staying warm. Expect consumption to climb 15–25% during cold snaps. A practical habit: toss a tablespoon of scratch grains per bird at dusk in winter — the slow digestion of whole grains generates heat overnight while birds huddle on the roost. Just keep scratch to no more than 10% of total intake, since it is low in protein.
2. Heat Suppresses Appetite
Above 85°F, hens naturally eat 10–15% less. This is normal and not worth fighting with treats — what matters in a heat wave is water, which can double from the usual one pint per hen per day to two pints at 90°F+. Egg production may dip for a week or two; it typically recovers as temperatures ease.
3. Free-Range Access Cuts Commercial Feed 20–30%
Birds with genuine pasture access — grass, seeds, insects, worms — supplement a meaningful share of their diet themselves. University extension trials and countless backyard records land on the same range: 20–30% less purchased feed during the growing season. Two caveats: the savings disappear in winter when forage is gone, and a bare dirt run supplies almost nothing. Chickens on a 10×10 gravel lot still eat a full ration.
4. Feed Form and Waste
Pellets waste less than mash — birds can't sift out the fines they don't like, and studies of mash vs. pellet feeding consistently show 10–15% less spillage with pellets. A trough-style feeder hung at back height and filled only two-thirds full also cuts waste dramatically compared to a deep dish on the floor. If your hens scatter feed like confetti, you may be buying 20% more than the tables above suggest. Fermenting feed is another proven trim: soaking feed for 24–72 hours improves digestibility enough to cut total consumption 10–15%.
5. Age and Life Stage
Consumption ramps up fast in a bird's first months. A day-old chick nibbles a few tablespoons of starter a week; by 16–20 weeks a growing pullet is eating near-adult quantities without yet laying. Once a hen passes her second or third laying season and production slows, her intake eases slightly too. Molting hens often drop feed intake noticeably for a few weeks while feathers regrow, then rebound.
6. Egg Production Level
Every egg represents roughly 20 g of feed input under good management — that is the working figure many small-flock economics guides use. A high-producing hybrid laying 300 eggs a year eats noticeably more than a heritage hen laying 150, even at the same body weight. If you want to see how intake translates into cost per dozen, the Egg Production Calculator estimates laying rates and feed efficiency for your flock profile.
How to Feed: Free-Choice vs. Measured Rations
Most backyard keepers feed free-choice: the feeder stays full and birds regulate themselves. It works because chickens are remarkably good at eating what they need — layers eating a balanced 16% protein ration rarely overeat to the point of harm. The downsides are waste and rodents, so use a waste-limiting feeder and store feed in a sealed metal bin.
Measured feeding — dishing out a fixed amount once or twice a day — gives you tighter control and eliminates most spillage. The rule of thumb: never ration a laying hen below about 0.2 lb per day, or shell quality and body condition suffer. Timing matters less than people think, although roughly three-quarters of a hen's intake happens in the hours around daylight, so filling the feeder in the morning matches her natural rhythm.
Whichever method you choose, track consumption for a full month before deciding your birds are over- or under-fed. Weigh one feeder serving, note the refill dates, and compare against the tables above. If you prefer paper to spreadsheets, the Chicken Feed Chart printable gives you a fill-in sheet for weekly consumption and bag reorders — stick it on the feed bin lid.
Frequently Asked Questions
How much feed does one chicken eat per day?
About 0.25 lb (113 g) per day for a typical laying hen — half a cup, 1.75 lb per week, and roughly 7.5 lb per month. Adjust to 0.30 lb for heavy breeds like Orpingtons and Australorps, or about 0.10 lb for bantams.
How many bags of feed does a flock of 6 hens use per month?
Six layers eat about 45 lb per month, so a single 50 lb bag lasts close to five weeks. That is roughly 12 bags a year — $190–260 annually at $16–22 per bag.
Do chickens eat more in winter?
Yes — expect 15–25% more feed during freezing weather as birds burn calories for warmth, and consider a small evening scratch ration. In summer heat above 85°F, intake drops 10–15% instead.
How much less feed do free-range chickens eat?
With real pasture and insects available, 20–30% less purchased feed during the growing season. In winter, or on a bare dirt run, free-ranging saves essentially nothing.
Should feed be available all day?
Free-choice feeding is the standard and works well for layers. If you prefer measured rations, keep a laying hen at or above 0.2 lb per day and feed in the morning, when most natural eating occurs.
