A flock of six hens can eat through a 50-pound bag of layer feed in about three weeks. Most new chicken keepers hear that number and immediately wonder: am I overfeeding? Underfeeding? Is that bag disappearing into the bedding or into actual chickens? Getting the daily feed amount right matters more than most people realize, because both overfeeding and underfeeding carry real consequences, from obesity and fatty liver disease to dropped egg production and feather loss.
How Much Feed Does One Chicken Actually Need Per Day?
The standard baseline is roughly 1/4 pound (about 4 ounces or 113 grams) of feed per chicken per day. That’s the number most poultry nutritionists and extension offices work from, and it holds up pretty well in practice for a standard-sized laying hen.
But here’s where it gets more nuanced. That quarter-pound figure assumes a few things: a moderately active hen, comfortable temperatures, no molt, and limited access to forage. Change any of those variables and the number shifts.
A 5-pound leghorn-type hen eating commercial layer pellets in a temperate climate might hit that 4-ounce mark almost exactly. A 9-pound Orpington going through a heavy molt in October, ranging across a large yard all day? She might eat closer to 6 ounces without batting an eye. Breed, body size, season, activity level, and whether she’s free-ranging all push that daily intake up or down.
As a quick rule of thumb for planning feed purchases:
- Small breeds (bantams): 2 to 3 ounces per day
- Standard laying breeds: 4 to 4.5 ounces per day
- Heavy dual-purpose breeds: 4.5 to 6 ounces per day
Multiply by the number of birds and you’ve got your daily flock total. A flock of 8 standard hens, for example, needs roughly 32 to 36 ounces (2 to 2.25 pounds) of feed daily. Scale that out over a month: approximately 60 to 67 pounds. That lines up with the real-world bag consumption most experienced keepers report.
Free Choice vs. Measured Feeding: Which Method Is Better?
This is the question that sparks genuine debate in the poultry community. Both work. But they work differently depending on your setup.
Free choice feeding means keeping a feeder full at all times and letting birds eat whenever they want. Most laying hens self-regulate reasonably well. They’re not dogs, they won’t typically gorge themselves into obesity on a balanced feed if they’re getting enough exercise and outdoor time. The major advantage is simplicity: you fill the feeder every day or two, and the birds eat what they need. It also prevents the social hierarchy from causing problems, since submissive hens that get bullied away from the feeder during a timed feeding window still have access throughout the day.
Measured or scheduled feeding means offering a set amount once or twice daily, usually in the morning and late afternoon. You get precise control. You’ll spot health problems early, too. A hen eating significantly less than usual is often the first sign something’s wrong. And it reduces overnight feed sitting in the feeder where rodents can find it.
I’ve had better results with free choice feeding for backyard flocks that have outdoor access. The birds stay active, their appetites stay regulated, and egg production stays consistent. Measured feeding makes more sense in high-humidity climates where wet feed spoils quickly, in flocks with obesity-prone breeds, or when you’re actively monitoring for illness.
One practical middle ground: use a feeder with enough capacity to keep feed available all day, but fill it each morning and note roughly how much gets consumed. You get the benefits of both approaches.
If you’re still figuring out your feeding setup overall, our guide on chicken feed types explained covers the differences between crumbles, pellets, and mash, which can also affect how much your birds actually eat and waste.
How Season, Molt, and Life Stage Change Daily Feed Needs
10 Chicken Coop Mistakes you DON'T want to Make ! · Carolina Coops® on YouTube
| Life Stage / Breed Type | Daily Feed Amount | Notes |
|---|---|---|
| Bantams (small breeds) | 2-3 ounces | Lower body weight |
| Standard laying breeds | 4-4.5 ounces | Baseline for most flocks |
| Heavy dual-purpose breeds | 4.5-6 ounces | Larger frame, higher consumption |
| Cold weather (below 35°F) | +10-25% above baseline | Increased calorie burn |
| Molt season | Increased, 18-20% protein feed | Feathers require extra protein |
| Hot weather | Reduced from baseline | Heat suppresses appetite |
| Broody hen | Slightly reduced | Limited foraging time |
| Week-old chick | ~0.5 ounces | Chick starter feed |
| 16-week pullet | Approaching adult intake | Still on grower/starter feed |
Static feeding amounts are a starting point, not a permanent prescription. Chickens’ nutritional demands change significantly across the year.
Cold weather: Chickens burn more calories keeping warm. In temperatures below 35°F, expect your hens to eat 10 to 25 percent more feed. A bird that eats 4 ounces in July might need 5 ounces by December. Don’t cut back on feed in winter hoping to save money. That’s exactly the wrong time to do it.
Hot weather: Heat suppresses appetite. Birds eat less in summer, sometimes noticeably so. They’ll compensate partially by drinking more water (which is why waterer capacity matters so much in July). Egg production may dip a bit, correlated with the reduced calorie intake.
Molt: The annual molt is a significant nutritional event. Feathers are roughly 85 percent protein, and a hen growing them back needs extra protein, sometimes as much as 18 to 20 percent crude protein instead of the standard 16 percent. Daily feed consumption often increases during this period. Don’t be alarmed if your molting hens seem to be eating you out of house and home.
Pullets vs. mature hens: Young pullets from hatch to about 18 weeks should be on chick starter or grower feed, not layer feed. Their daily intake scales up as they grow: a week-old chick eats maybe 0.5 ounces per day; by 16 weeks, she’s approaching adult consumption. Switching to layer feed too early (before 18 weeks) introduces calcium levels that can damage young kidneys.
Broody hens: A broody hen sitting on a nest often forgets to eat. She’ll get up once or twice daily to eat, drink, and defecate. Make sure feed and water are close to the nest so she doesn’t have to travel far during her brief breaks. She’ll eat a bit less than normal during the full broody cycle.
What Scraps and Foraging Do to the Equation
Treats, kitchen scraps, and free-ranging all displace commercial feed to some degree. This is fine, but it needs to be managed thoughtfully.
The 90/10 rule is the standard guidance: treats and scraps should make up no more than 10 percent of a chicken’s total daily diet. For a standard hen eating 4 ounces a day, that’s about 0.4 ounces of treats max. That’s not much. A handful of scratch grains scattered across the run quickly adds up across a flock.
Free-ranging complicates feed calculations. A hen with access to a lush pasture in spring or summer will supplement her diet meaningfully with bugs, worms, seeds, and greens. During peak foraging seasons, some keepers report their flocks consuming 20 to 30 percent less commercial feed. That’s real savings, but you can’t count on it year-round. When the grass dies off in autumn, commercial feed becomes the primary nutrition source again.
Don’t forget that chickens need grit for chickens to properly digest anything that isn’t a processed feed. If your hens aren’t free-ranging on ground where they can pick up small stones, you’ll need to supply insoluble grit separately. Without it, whole grains and treats can sit undigested in the gizzard.
Some foods should never make it into the scraps bucket regardless of portion size. Our article on foods chickens cannot eat covers the full list, but avocado, dried beans, and anything moldy are the most dangerous ones to watch for.

Getting consistent with feeding pays off quickly in flock health and egg production. Here’s how to dial it in.
Step 1: Establish a baseline. For one week, measure exactly how much feed you put into the feeder each day and weigh what’s left at the same time the next morning. The difference is your flock’s actual daily consumption. Do this when there are no unusual variables: no heat wave, no molt, no new birds.
Step 2: Adjust for body condition. Pick up each hen weekly (or monthly at minimum) and feel her keel bone. It should be palpable but not sharp like a knife blade. If you can feel every bump and ridge of the keel with no fat cover, she’s underweight. If you struggle to find the keel through a thick layer of fat, she’s overweight. Adjust feed accordingly.
Step 3: Watch the feeder timing. If your feeder empties by noon and your hens spend the afternoon pacing and pecking frantically at nothing, you’re underfeeding. If there’s feed left over the next morning and it’s getting stale or damp, you might be overfeeding, or your feeder design is causing waste.
Step 4: Account for seasonal shifts. Revisit your baseline measurement in October and again in April. Cold weather birds need more; warm weather birds need a little less. Don’t set a number in June and forget it until March.
Step 5: Track egg production. A well-fed laying hen at peak production should lay 5 to 6 eggs per week depending on breed. Drops in production that can’t be explained by molt, daylight hours, or stress often trace back to inadequate nutrition, particularly protein and calcium.
For a feeder that minimizes waste and prevents overnight rodent access, a treadle-style feeder like the Grandpa’s Feeders Automatic Chicken Feeder is worth every penny for flocks of 6 or more birds. It pays for itself in reduced feed waste within a few months.
Getting your feeding amounts right isn’t a one-time task you figure out in the first week and never revisit. It’s an ongoing practice that shifts with the seasons, your flock’s life stage, and what’s happening in your yard. Pay attention to body condition, monitor the feeder, and let your hens tell you what they need. They’re usually pretty clear about it.
