Feed a laying hen about 100 to 150 grams of complete feed per day, or roughly 0.25 pound per bird. Use that as the planning baseline, then adjust for body size, age, production stage, weather, and how much feed your feeder wastes.

You know the scene. The feeder looks empty before lunch, a few hens are scratching feed out onto the ground, and one bird is laying thin-shelled eggs while the others seem fine. The question isn't only how much feed you pour into the trough. It's how much balanced nutrition each hen consumes.

A scoop can hide that answer. Feed density changes between pellets, crumbles, and mash, while feeder design and flock behavior determine how much lands in the litter instead of in a crop. The practical keeper's job is to measure feed disappearance, watch the birds and eggs, and make small adjustments rather than chasing one supposedly perfect number.

The Daily Feeding Baseline for Laying Hens

For adult layers under ordinary conditions, plan around 100 to 150 grams of complete layer feed per hen per day, approximately 0.22 to 0.33 pound. Extension guidance commonly uses the quarter-pound figure, while more specific nutrition references often place mature intake near 110 to 115 grams or 120 to 130 grams, depending on bird size, breed, temperature, and stage of lay. The Alabama Cooperative Extension guidance on feeding laying hens describes the broader 100 to 150 gram planning range.

Grams are more useful than cups because a cup isn't a consistent unit of nutrition. A scoop of dense pellets weighs differently from the same scoop of fluffy crumbles, and a feeder that allows scratching can make an apparently generous ration look inadequate. Weigh the feed you normally use, record the amount placed in the feeder, then weigh or estimate what remains after a full day.

Daily feed baseline by hen size

These are planning bands, not strict prescriptions. A small, active hen may eat more than a quiet large bird, especially if she's producing heavily or living outdoors in cold weather. Conversely, a flock may appear to consume 150 grams per bird when much of that amount is spilled, soiled, or taken by rodents.

Practical rule: Measure what disappears from the feeder, then inspect the ground before deciding your hens need more.

Flock budgeting becomes easier when you use grams per hen per day rather than scoops. The cost of feeding chickens can then be calculated from real consumption, not from a scoop whose weight changes between feed types.

Housing management matters too. A covered feeder with openings that limit tossing usually gives a more honest picture of intake than a shallow pan. If you're reviewing broader hobby-farm risk and management advice, Farm & Country Insurance's advice for hobby farms is a useful resource alongside your feeding records.

Adjusting Feed Amounts by Age and Production Stage

A pullet shouldn't jump from chick feed straight to a full adult ration because the bag says “chicken feed.” Young birds build frame, muscle, feathers, and reproductive capacity in stages. Starter feed belongs to the earliest growth period, followed by grower or developer feed as the pullet matures, with layer feed introduced around the onset of lay according to the feed label and the bird's development.

The useful progression is gradual. Poultry Hub Australia reports intake rising from about 37 grams per bird per day at 6 weeks to about 80 grams at 17 weeks, with mature layers stabilizing near 100 to 105 grams as they reach a body weight of about 1,700 to 1,800 grams. See the Poultry Hub nutrient requirements for egg-laying chickens for that age and maturity benchmark.

Read the flock, not just the calendar

At six weeks, offer starter or an appropriate transition ration and monitor body development rather than forcing an adult portion. Through the pullet stage, increase the amount as appetite and size rise. At point of lay, feed consumption can climb quickly because the hen is now supporting egg formation as well as her own body.

A practical sequence looks like this:

• Chick stage: Keep starter feed available in a form young birds can eat easily.
• Pullet stage: Move to grower or developer feed and step intake upward as the flock grows.
• Laying stage: Introduce layer ration when birds are approaching production, not merely because they have reached a convenient date.

Feed needs often remain higher during the early production period, then vary with body size, egg output, molt, and weather. A young pullet that eats less than a mature layer isn't necessarily underfed, but a bird with poor development, a sharp keel, or delayed production deserves closer inspection.

Black soldier fly larvae can fit as a supplemental treat for pullets and layers. The USA GROWN BLACK SOLDIER FLY LARVAE FOR CHICKENS catalog description lists 36 to 42 percent crude protein and states that the larvae offer 75 times more calcium than mealworms, so they should be treated as a concentrated supplement rather than a replacement for a correctly formulated grower or layer ration.

Protein, Calcium, and What Layer Rations Must Deliver

A layer can have a full feeder and still fall short nutritionally if her ration lacks usable protein, calcium, or energy. Standard layer feeds commonly contain about 16 to 18 percent protein and roughly 3.5 to 4.5 percent calcium, ranges documented in the Agrifarming guide to daily chicken feed. Those percentages support egg production, muscle, feathers, and shell formation, but only when the hen eats enough of the feed.

Protein supplies the egg's organic components and supports feather replacement and tissue repair. Calcium forms the shell with help from phosphorus and vitamin D3. Methionine and other amino acids matter too, because a crude-protein percentage does not show whether the feed contains the right building blocks in useful proportions.

Match the ration to actual intake

The label describes nutrient density, not what reaches the bird. A hen that eats less because of heat, illness, crowding, or stale feed also takes in less protein, energy, and calcium, even if the ration is correctly formulated.

Merck Veterinary Manual places laying-hen intake at 80 to 120 grams per bird per day, depending on production and diet density. Its nutrition tables list roughly 15 grams of protein and 299 kilocalories of metabolizable energy for hens producing at least 80 percent, compared with about 12.5 grams of protein and 250 kilocalories for hens around 50 percent production. These figures appear in the Merck Veterinary Manual poultry nutrition requirements.

Egg changes often appear before the feeder looks empty. Thin, rough, or shell-less eggs, falling production, and poor feather condition justify checking feed freshness, water access, total intake, and flock competition. Avoid correcting every shell problem by mixing extra calcium into the main ration. Complete layer feed already contains calcium, while a separate source allows actively laying hens to take more without pushing the same mineral load onto pullets.

For a practical visual explanation of egg nutrition and layer nutrients, watch this short reference:

Shell quality also depends on the calcium source and how birds can access it. Compare options in this guide to the best calcium supplement for chickens, but keep the complete layer ration as the nutritional foundation.

When Heat Stress Changes Everything

Hot weather invalidates the lazy assumption that an available feeder guarantees adequate nutrition. In one commercial-layer report, intake fell from 86.7 grams per day at control temperature to 41.6 grams per day under heat stress, a finding summarized in the Ontario guidance on heat stress in commercial layers. The same source notes that feed intake drops above 28°C and that average energy intake loss is 1.6 percent per 1°C above 20°C.

That changes the calculation. You may offer the usual amount, but a panting hen can consume far less, so her daily intake of protein, energy, and calcium falls. Adding more feed to a hot feeder often creates waste rather than solving the nutritional shortfall.

Change density and timing

Put the largest share of the ration out during the coolest part of the morning, then offer the remaining feed later when temperatures ease. Keep water clean, shaded, and easy for every bird to reach. If hens eat less, a properly formulated, more nutrient-dense ration can help, but don't improvise by adding random concentrates without checking the feed label.

Watch the eggs as well as the birds. Shell quality may slide when calcium intake and mineral use are disrupted. A hen that pants heavily, isolates herself, or stops approaching the feeder needs cooling, water, and prompt attention, not just a larger portion.

Cold, hydrating produce can encourage interest in food, but treats should remain supplemental. Wet mash may improve palatability for some flocks, yet it spoils quickly in warm conditions, so remove leftovers promptly. Heat management works best when feeding time, water, shade, ventilation, and ration density are handled together.

Treats, Scraps, and BSFL as Supplemental Feed

Complete layer feed should do most of the nutritional work. Treats are useful for training, enrichment, and variety, but they dilute the ration when they displace too much of it. The commonly used backyard limit is under 10 percent of daily intake, which works out to about 10 to 15 grams per hen per day when the flock's baseline is 100 to 150 grams. That guidance and the product data for dried larvae should be interpreted together, because a small quantity of a concentrated supplement is different from a large bucket of low-density scraps.

Black soldier fly larvae are attractive because they provide protein and calcium in a form hens readily eat. The Pure Grubs catalog describes dried BSFL at 36 to 42 percent crude protein, while its snapshot also lists 30 to 40 percent healthy fats. Those figures make larvae a supplement, not a complete replacement for layer feed.

Compare the choices

The dried black soldier fly larvae guide is useful for thinking about larvae as a concentrated addition rather than a free-choice staple. Scatter them in the run so hens forage, or use a small amount during handling and training. Don't fill the main feeder with treats, even when the flock ignores layer pellets afterward.

For scraps, choose plain foods such as leafy greens, squash, oats, and fruit. Avoid avocado pits, chocolate, raw beans, and anything moldy. Scratch grains can be especially easy to overuse because hens enjoy them, but enjoyment isn't evidence of a balanced ration.

A separate dish of oyster shell can make sense for actively laying hens, especially when shell quality is inconsistent. Keep it separate from the main feed so birds that don't need extra calcium aren't forced to consume it. If shells remain thin, first check feed intake, age, heat, illness, and water before assuming the answer is another treat.

A Simple Daily Feeding Rhythm That Works

A flock that finishes feed too quickly, leaves damp clumps, or lets dominant hens control the feeder needs a routine you can observe. Start with a measured morning portion, keep clean water available, and reserve part of the complete ration for late afternoon. This makes waste and access problems easier to separate from genuine appetite.

At first light, or when you open the coop around 6 to 7 a.m., place about 70 grams of complete layer feed per hen in the main feeder. Wait until that balanced feed is available before scattering a tablespoon of scratch or a small amount of BSFL in the run. Treats belong around the ration, not in place of it. The schedule is a practical starting point, while the flock's total daily intake remains the stronger guide.

Use the day as a diagnostic tool

Check water first at midday. A hen hanging back may be ill, overheated, or blocked from the feeder by flock bullying. Look for damp feed, mold, and excessive fines inside the feeder, then inspect the ground for tossed pellets. During hot weather, poor water access can reduce feed intake faster than a small change in portion size.

About an hour before dusk, offer another 30 grams per hen in the example schedule. This gives hens access to complete feed as they prepare to roost, but remove or secure it overnight if rodents are a problem.

• Feeder height: Set openings around the birds' back height to reduce scratching and waste.
• Leftover feed: Remove wet or moldy feed instead of mixing it into fresh feed.
• Water checks: Refresh dirty water immediately, especially during hot weather.
• Body condition: Feel the keel monthly. A sharp keel suggests poor condition, excessive padding suggests excess weight, and a smooth, lightly padded keel is the target.

Keep a short record of feed placed, feed remaining, egg count, shell quality, and unusual behavior. Comparing those notes across weather and production changes shows whether hens are eating the ration or scattering it. Adjust the measured portions only after checking access, water, feed freshness, and treat use.

Fine-Tuning Your Feeding Plan Week to Week

The most dependable feeding plan is a feedback loop. Start with the baseline, then compare what you offered with what vanished, what the birds look like, and what the eggs tell you. A change in weather, molt, flock hierarchy, or production can make last month's portion unsuitable.

Run a weekly check

Record the amount placed in the feeder and the amount left before adding more. Separate genuine consumption from spilled feed, and inspect the litter around the feeder for waste. Then review four signals:

• Body condition: Feel the keel and compare each bird with her previous condition, not only with flock mates.
• Egg output: Note whether production is holding steady or changing alongside feed disappearance.
• Shell quality: Flag thin, cracked, rough, or soft shells before the issue becomes widespread.
• Flock access: Watch subordinate hens during feeding, because a full feeder doesn't help a bird that cannot reach it.

Make one change at a time. If body condition is falling and feed waste is minimal, add 10 grams per hen per day and reassess. That adjustment should be tied to measured condition, not made automatically for every flock. If shells thin while hens receive plenty of complete feed, reduce treats to under 5 percent of intake, check water and heat exposure, and offer a separate calcium source rather than endlessly increasing the base ration.

Avoid the common traps

Free-choice layer feed can work for some flocks, but it becomes expensive when birds scatter it or fill up on treats. Over-supplementing calcium can also create problems, especially when young birds share the same feed area, so keep calcium sources separate and intended for laying hens.

Heat waves deserve a different response from cold weather. If hens eat less, improve access and cooling, feed during cooler hours, and consider a properly formulated higher-density ration instead of piling more feed into the trough. The Merck nutrition reference supports the central principle: match diet density to actual consumption and production.

Feeding laying hens isn't a fixed scoop measurement. Revisit the 100 to 150 gram baseline whenever age, production, temperature, housing, or flock condition changes, then adjust from evidence gathered at your own feeder.
