Feed Budgeting for Layer Flocks: Calculating Costs and Quantities

By Dr. Zubair Khalid, DVM, MS, PhD · 2026-08-14

Key Takeaways

• Feed constitutes 60-70% of layer operation costs; accurate budgeting is critical for profitability, with a baseline daily intake of 0.30 pounds per hen.
• Feed cost per dozen eggs is calculated as (daily intake per hen x feed price per pound x 12) / eggs per hen per day, with typical feed conversion ratios of 1.7-2.2 lbs/dozen.
• Winter feed intake increases by approximately 1% for every degree Fahrenheit below 65°F due to thermoregulation needs, necessitating budget adjustments.
• Maintaining a minimum 2-week, preferably 4-6 week, feed inventory is crucial to mitigate supply disruptions and price volatility.
• Sudden feed intake drops exceeding 10% over 3 days, or significant changes in water consumption or egg production, warrant immediate veterinary or extension agent consultation.

Feed is the single largest recurring expense in any layer operation, typically consuming 60 to 70 percent of total production costs. Yet many flock owners cannot state with confidence what their birds actually eat per day, what that intake costs per dozen eggs, or how much feed they need to have on hand heading into winter or a supply disruption. This guide walks you through the full process of building a working feed budget for a layer flock, from measuring daily consumption to calculating cost per dozen eggs, projecting seasonal needs, managing inventory, and adjusting rations as birds age. It is written for small and mid-scale producers, homesteaders with 20 hens, and commercial managers running several thousand layers who want a practical, repeatable system for controlling their largest input cost.

At a Glance

• A standard laying hen eats 0.25 to 0.35 pounds of feed per day, or roughly 1.5 to 2.0 pounds every 6 days. Use 0.30 pounds per hen per day as your planning baseline.
• Feed cost per dozen eggs equals daily feed intake per hen multiplied by feed price per pound, multiplied by 12, divided by eggs per hen per day.
• A flock of 100 hens eating 0.30 pounds per day at $0.25 per pound spends $7.50 per day on feed, or about $225 per month.
• Expect feed conversion of 1.8 to 2.2 pounds of feed per dozen eggs for brown egg layers and 1.7 to 2.0 for white egg strains under good management.
• Store a minimum of 2 weeks of feed on hand, and preferably 4 to 6 weeks if you depend on a single feed mill or face seasonal delivery challenges.
• Feed intake rises 1 percent for every 1 degree Fahrenheit below 65 degrees, so winter budgets must account for cold weather consumption.
• Track feed usage weekly and egg production daily. Compare actual intake to expected intake monthly and adjust purchasing decisions accordingly.
• Call your veterinarian or extension agent if feed intake drops more than 10 percent over 3 days, if water consumption changes suddenly, or if egg production falls faster than normal molt patterns explain.

Why Feed Budgeting Matters for Layer Flocks

Feed budgeting is not bookkeeping for its own sake. It is the difference between knowing your cost of production and guessing at it. Layer flocks convert feed to eggs with remarkable efficiency, but that efficiency depends on matching intake to need. Overfeed and you waste money on fat birds that lay no better than lean ones. Underfeed and you lose egg size, shell quality, and persistency of lay. The margin between profit and loss in eggs is thin, often a few cents per dozen, so small errors in feed management multiply quickly across a flock of any size.

A feed budget serves four distinct purposes. First, it tells you what your flock should eat so you can detect problems early. A healthy flock eats a predictable amount each day based on body weight, production rate, and temperature. When intake deviates from that prediction, something is wrong, whether it is disease, poor feed quality, or environmental stress. Second, a budget tells you what to buy and when. Feed is bulky and perishable. Buying too much ties up capital and risks spoilage. Buying too little forces emergency trips to the mill and leaves you vulnerable to price spikes or supply interruptions. Third, a budget tells you what your eggs cost to produce. Cost per dozen eggs is the number that determines whether you can price eggs profitably, whether you should sell direct or wholesale, and whether the flock is worth keeping. Fourth, a budget forces you to plan for the future. Pullets coming into lay, peak production, molt, and culling all change feed demand. A budget that accounts for these phases keeps you ahead of the flock rather than reacting to it.

The financial stakes are substantial. A 500-bird flock eating 0.30 pounds per hen per day consumes 150 pounds of feed daily. At $0.25 per pound, that is $37.50 per day, $1,125 per month, and $13,500 per year. A 10 percent error in estimating intake, either over or under, is worth $1,350 annually on feed alone. For a 10,000-bird operation, the same error is $27,000 per year. Feed budgeting is therefore not an administrative chore. It is a direct profit lever.

Understanding Layer Feed Consumption

Before you can budget, you need a reliable estimate of what your birds actually eat. Feed intake in laying hens is governed by five main factors: body weight, rate of lay, environmental temperature, feed energy concentration, and management practices. Each of these shifts intake in predictable ways, and understanding them lets you anticipate changes before they cost you money.

Body weight is the foundation of intake. A hen eats to meet her energy requirement first, and maintenance energy scales with body weight. A standard White Leghorn laying hen weighs 3.5 to 4.0 pounds and eats about 0.22 to 0.25 pounds of feed per day at moderate temperatures. A heavier brown egg layer, such as a Rhode Island Red or Barred Plymouth Rock, weighs 5.5 to 6.5 pounds and eats 0.28 to 0.35 pounds per day. The difference is not breed preference. It is the cost of maintaining a larger body. When you calculate expected intake, start with the breed standard weight for your strain, then adjust for actual flock weight. Underweight birds eat less but also lay smaller eggs and produce fewer of them. Overweight birds eat more without laying proportionally more.

Rate of lay is the second major driver. A hen laying at 90 percent production has a much higher nutrient demand than one laying at 50 percent. Each egg contains roughly 6 grams of protein and 5.5 grams of fat, and the hen must mobilize those nutrients daily. Feed intake rises as production rises, peaks alongside peak lay, and falls as production declines. The relationship is not perfectly linear, but as a rule of thumb, a hen at peak lay eats 25 to 30 percent more than the same hen out of production. This matters for budgeting because you cannot use a single average intake figure for the whole year. You must scale intake to the production curve.

Environmental temperature is the factor most often underestimated by new flock owners. Hens are comfortable between 65 and 75 degrees Fahrenheit. Below 65 degrees, they burn extra calories to stay warm, and feed intake rises by about 1 percent for each degree the temperature drops. At 35 degrees, a hen needs roughly 30 percent more feed than at 70 degrees. At 20 degrees, she needs 45 percent more. This is not optional consumption. It is thermoregulation. If you do not increase feed during cold weather, the hen will draw on body reserves, egg production will fall, and egg size will shrink. Conversely, above 80 degrees, intake falls as hens try to shed heat. A hen at 90 degrees may eat 15 to 20 percent less than at 70 degrees, which is why heat stress depresses egg production so quickly.

Feed energy concentration determines how much feed a hen must consume to meet her energy needs. A standard layer ration contains about 1,275 to 1,350 kilocalories of metabolizable energy per pound. If you feed a higher-energy ration, hens eat less by weight. If you feed a lower-energy ration, they eat more. This is a critical point for budgeting because feed price per pound is not the same as feed cost per hen per day. A cheap, low-energy feed may actually cost more per day if hens must eat more of it to get the same energy. When comparing feed prices, always calculate cost per hen per day, not cost per bag.

Management factors also move intake. Feeder space, feeder design, and feeding frequency all influence how much hens eat. Hens need at least 3 inches of feeder space per bird in a trough system or adequate access points in a tube feeder. If feeder space is inadequate, low-ranking birds eat less and production suffers. Feed that is stale, moldy, or contaminated reduces intake. Water quality and availability matter too. A hen drinks about 2 parts water for every 1 part feed, and if water is restricted or unpalatable, feed intake falls within hours.

How to Calculate Daily Feed Intake for Your Flock

You cannot budget accurately without measuring what your flock actually eats. Estimating from breed charts is a starting point, but your birds are unique. Their weight, production, housing, and environment all differ from the textbook. Measuring actual intake is straightforward and takes 10 minutes per week.

Start with a clean, empty feeder system. Weigh the feed you put into the feeders, or weigh the feeders themselves before filling. Record the starting weight. After 24 hours, weigh what remains. The difference is what the flock consumed. Divide by the number of hens to get per-hen daily intake. Repeat this for 3 to 7 consecutive days and average the results to smooth out day-to-day variation. One day of measurement can be misleading because hens may eat more or less based on weather, disturbance, or feeder adjustment. A weekly average is far more reliable.

For tube feeders, the process is the same but slightly more involved. Weigh the empty feeder, fill it, weigh it again, and record the difference as the starting feed weight. After 24 hours, weigh the feeder with remaining feed. The difference is consumption. If you have multiple feeders, weigh each one. For trough feeders, you can weigh feed as you add it and then collect and weigh the leftovers at the end of the period. This is messier but accurate.

Do not forget to account for waste. Feed that is spilled, scattered, or kicked out of the feeder is still feed you paid for, but it does not show up in a simple weigh-back. If you see significant buildup of spilled feed under feeders, you are overfilling or using the wrong feeder height. Adjust feeder levels so the lip of the feeder is at the height of the hen's back. Fill tube feeders only one-third to one-half full to reduce waste from birds flicking feed out. If waste is a persistent problem, measure it by placing a catch tray under the feeder and weighing what accumulates over a week. Add that to your consumption figure so your budget reflects true feed disappearance, not just what the birds ate.

Once you have measured actual intake, compare it to the expected intake for your breed, weight, and production level. Your extension service or feed supplier can provide intake tables for your specific strain. If actual intake is within 5 percent of expected, your budget is on track. If it is more than 10 percent off, investigate. Low intake may indicate poor feed palatability, disease, heat stress, or feeder problems. High intake may indicate cold stress, low feed energy, or excessive waste.

Calculating Feed Cost per Dozen Eggs

The single most useful number for a layer operation is feed cost per dozen eggs. This is the number that tells you whether your eggs are profitable and by how much. It is also the number that lets you compare feed options, evaluate management changes, and decide when to cull a flock.

The calculation requires three pieces of data: daily feed intake per hen in pounds, feed price per pound in dollars, and daily egg production per hen expressed as a decimal. The formula is:

Feed cost per dozen eggs = (Daily feed intake per hen x Feed price per pound x 12) / Eggs per hen per day

Let us work through an example. Suppose you have a flock of brown layers averaging 5.5 pounds body weight, laying at 85 percent production, and consuming 0.30 pounds of feed per day. Your feed costs $0.25 per pound. Daily egg production per hen is 0.85 eggs. The calculation is:

(0.30 x $0.25 x 12) / 0.85 = $0.90 / 0.85 = $1.06 per dozen

That means feed alone costs $1.06 for every dozen eggs your flock produces. If you sell eggs for $3.00 per dozen, you have $1.94 per dozen to cover labor, housing, depreciation, mortality, and profit. If you sell for $2.00 per dozen, you have $0.94, which may not cover your non-feed costs.

Now change one variable. Suppose the same flock is laying at 60 percent production, which is typical for a flock late in its first laying cycle. Daily egg production per hen is 0.60. The calculation becomes:

(0.30 x $0.25 x 12) / 0.60 = $0.90 / 0.60 = $1.50 per dozen

The feed cost per dozen jumped from $1.06 to $1.50 even though feed price and intake did not change. This is the hidden cost of declining production. As hens age and lay fewer eggs, the feed cost per dozen rises because the same daily feed cost is spread over fewer eggs. This is why many producers cull or molt flocks when production drops below a threshold where feed cost per dozen becomes unsustainable.

The same formula works in reverse for planning. If you know your target feed cost per dozen, you can solve for the maximum feed price you can pay. Suppose you want feed cost per dozen to stay below $1.20. With intake at 0.30 pounds and production at 85 percent, the maximum feed price is:

Maximum feed price per pound = (Target cost per dozen x Eggs per hen per day) / (Daily intake x 12)

= ($1.20 x 0.85) / (0.30 x 12) = $1.02 / 3.60 = $0.283 per pound

If feed prices rise above $0.283 per pound, you either need higher production, lower intake, or a higher egg price to maintain your target feed cost.

For a quick estimate, you can use the common rule of thumb that a hen eats about 1.5 to 2.0 pounds of feed per dozen eggs produced. This is the feed conversion ratio for eggs, and it is a useful sanity check. If your calculated feed per dozen is above 2.2 pounds, look for waste, low feed quality, or excessive cold stress. If it is below 1.7 pounds, verify your measurements, because very few flocks achieve that efficiency.

Building a Monthly Feed Budget

A feed budget is a projection of feed needs and costs over a defined period, usually a month. It answers two questions: How much feed will I need, and how much will it cost? The process is simple once you have your intake baseline, but it requires you to think ahead about production changes, weather, and flock size.

Start with your current flock inventory. Count the number of hens in production, the number of pullets coming into lay, and the number of birds you plan to cull or sell during the month. For each group, estimate the average daily feed intake per bird. Use your measured intake for the laying flock. For pullets, use the intake appropriate for their age and weight. A 16-week-old pullet eats about 0.20 to 0.25 pounds per day. A 20-week-old pullet just coming into lay eats 0.25 to 0.28 pounds. Adjust for expected weather. If the month is typically cold, increase intake estimates by 1 percent for each degree below 65 degrees average temperature.

Multiply the number of birds in each group by the daily intake to get total daily feed for that group. Add the groups together to get total daily feed for the flock. Multiply by the number of days in the month to get monthly feed quantity. Multiply by your feed price per pound to get monthly feed cost.

Here is an example. A farm has 200 laying hens averaging 0.30 pounds per day and 50 pullets at 0.22 pounds per day. It is January, and the average temperature is 35 degrees, which is 30 degrees below the 65-degree comfort threshold. Laying hens need a 30 percent intake increase, so their adjusted intake is 0.30 x 1.30 = 0.39 pounds per day. Pullets need the same adjustment, so their intake is 0.22 x 1.30 = 0.286 pounds per day.

Daily feed for layers: 200 x 0.39 = 78 pounds Daily feed for pullets: 50 x 0.286 = 14.3 pounds Total daily feed: 92.3 pounds Monthly feed for 31 days: 92.3 x 31 = 2,861 pounds At $0.25 per pound: 2,861 x $0.25 = $715.25

If this farm did not adjust for cold weather and used the unadjusted intake of 0.30 and 0.22 pounds, the monthly feed would be:

Layers: 200 x 0.30 = 60 pounds per day Pullets: 50 x 0.22 = 11 pounds per day Total: 71 pounds per day Monthly: 71 x 31 = 2,201 pounds Cost: $550.25

The difference is 660 pounds and $165 per month. That is the cost of cold weather, and it is a real cost that must be in the budget. If you do not plan for it, you will run out of feed mid-month or face an unplanned purchase.

Repeat this calculation for each month of the year. Build a 12-month table with columns for flock size, expected production, expected intake, weather adjustment, total feed needed, and total feed cost. This annual budget becomes your planning tool for cash flow, feed purchasing, and flock replacement decisions. It also gives you a baseline against which to compare actual monthly usage. When actual feed disappearance exceeds the budget, you know to investigate waste, theft, or inaccurate bird counts. When it falls below budget, you know to check for disease, poor feed palatability, or measurement errors.

Feed Inventory Management for Layers

Feed inventory management is the practical side of budgeting. It is about having the right amount of feed on hand at the right time without tying up excessive capital or risking spoilage. The goal is to avoid two failure modes: running out of feed and holding feed so long it goes bad.

The first rule of feed inventory is to know your weekly consumption. Take your measured daily intake, multiply by 7, and that is your weekly feed disappearance. For the example flock above eating 92.3 pounds per day, weekly consumption is 646 pounds. Round up to 650 pounds for planning. This is the number you use for purchasing decisions.

The second rule is to set a minimum inventory level. For most operations, a 2-week supply is the absolute minimum. This covers delivery delays, mill breakdowns, and short-term price spikes. For operations in remote areas, or those relying on a single feed mill, a 4 to 6 week supply is safer. The cost of holding extra feed is the interest on your capital and the risk of spoilage. The cost of running out is lost production, which is almost always higher. A hen without feed for 24 hours will drop production for several days, and the lost eggs are worth far more than the interest on a few extra bags of feed.

The third rule is to store feed properly. Feed should be kept in a dry, rodent-proof, well-ventilated area. Moisture is the enemy. Feed with more than 12 percent moisture can grow mold, and moldy feed reduces intake and can cause illness. Store bagged feed off the floor on pallets or shelves, and rotate stock so the oldest feed is used first. If you buy bulk feed, use a clean, dry bin and clean it between loads. Check feed for signs of spoilage before feeding: off odors, visible mold, clumping, or insect infestation. If feed looks or smells wrong, do not feed it. The cost of discarding a bad batch is lower than the cost of a production drop or a sick flock.

The fourth rule is to track feed inventory weekly. Keep a simple log of feed on hand at the start of the week, feed purchased during the week, and feed used during the week. The difference between starting inventory plus purchases minus usage should equal ending inventory. If the numbers do not match, you have a problem: unaccounted waste, theft, or a counting error. A weekly inventory check takes 15 minutes and catches problems before they become costly.

For bulk feed systems, calibrate your bins or silos so you know how much feed you have at any time. Many producers use a simple dipstick or sight glass to estimate remaining feed. If you rely on delivery, establish a reorder point. For example, if you use 650 pounds per week and want a 4-week minimum, reorder when inventory drops below 2,600 pounds. This gives you time to schedule delivery before you hit the minimum.

Seasonal Adjustments to the Feed Budget

Feed intake and feed cost are not constant through the year. Temperature, daylight, and production cycles all shift feed demand, and a budget that ignores these shifts will be wrong for half the year. Seasonal planning is essential for both cost control and flock health.

Winter is the most demanding season for feed budgeting. As temperatures fall, hens eat more to stay warm. The 1 percent per degree rule means a flock in a 20-degree barn eats 45 percent more than the same flock at 70 degrees. For a 200-bird flock eating 60 pounds per day at 70 degrees, winter intake at 20 degrees is 87 pounds per day. That is 27 extra pounds per day, 189 extra pounds per week, and 810 extra pounds per month. At $0.25 per pound, that is $202.50 per month in additional feed for the same number of eggs. This is not optional spending. If you do not provide the extra feed, hens will lose body condition and production will fall.

Winter also affects feed quality. Feed stored in a cold barn can freeze, especially if it contains moisture. Frozen feed reduces intake because hens cannot eat it easily. Keep feed in a heated area if possible, or at least in a space that stays above freezing. Check waterers daily in winter because reduced water intake directly reduces feed intake. A hen that cannot drink will not eat.

Summer brings the opposite problem. Heat suppresses appetite, and hens may eat 15 to 20 percent less at 90 degrees than at 70 degrees. This is a problem because production continues, and the hen must meet her nutrient needs with less feed. The solution is not to force feed but to manage heat. Provide shade, ventilation, and cool water. Feed during the cooler parts of the day, such as early morning and late evening. Consider adjusting the ration to increase nutrient density so the hen gets more nutrients per pound of feed. Some producers add a small amount of fat to the ration in summer to increase energy density without increasing bulk.

Seasonal production cycles also affect feed demand. Pullets coming into lay in the fall will increase intake as they start producing. Hens going through a forced molt in late summer will eat less during the molt and more as they return to production. A flock nearing the end of its laying cycle will eat less as production declines. Your monthly budget should reflect these changes, not assume a constant intake all year.

Daylight is another seasonal factor. Hens need 14 to 16 hours of light for maximum egg production. As natural daylight shortens in fall, production declines unless you provide supplemental light. If you do not provide light, production falls, and feed cost per dozen eggs rises because the same feed is spread over fewer eggs. If you do provide light, hens continue to lay, and feed intake stays at production levels. The decision to light or not light is a budgeting decision because it directly affects both feed cost and egg revenue.

Adjusting Rations for Different Production Stages

Layer flocks move through distinct production stages, and each stage has different feed needs. A feed budget that treats all hens the same will either waste money on overfeeding or lose production to underfeeding. Understanding the stages lets you match feed to need.

The first stage is the pullet period, from hatch to point of lay. Pullets are not laying eggs, so their feed is an investment in future production. They need a grower ration with lower calcium and higher protein than a layer ration. Feed intake rises steadily as pullets grow, from about 0.05 pounds per day at day-old to 0.20 to 0.25 pounds per day at 16 to 18 weeks. The goal is to bring pullets into lay at the correct body weight, because underweight pullets lay smaller eggs and peak later. Your feed budget for pullets should be based on their age and target weight, not on a generic per-bird figure.

The second stage is the pre-lay or transition period, roughly 18 to 20 weeks. Pullets are approaching sexual maturity and need to build calcium reserves in their bones. Many producers switch to a pre-lay ration with higher calcium, around 2.0 to 2.5 percent, in the two weeks before the first egg. This prepares the hen for the heavy calcium demand of shell formation. Feed intake during this period is still moderate, about 0.22 to 0.26 pounds per day, but it is rising quickly.

The third stage is peak production, from about 25 to 35 weeks of age. This is when hens lay at the highest rate, often 90 to 95 percent for commercial strains. Feed intake peaks here too, reaching 0.28 to 0.35 pounds per day depending on breed and temperature. The ration must be at full layer formulation with 3.5 to 4.0 percent calcium and adequate protein, about 16 to 18 percent. This is the most expensive feeding period, but it is also the most productive, so feed cost per dozen eggs is usually at its lowest.

The fourth stage is mid-lay, from about 35 to 55 weeks. Production gradually declines from peak to around 75 to 80 percent. Feed intake may stay steady or decline slightly. Many producers continue the same ration through this period, though some switch to a slightly lower protein formulation to reduce cost. The key is to monitor egg size and shell quality. If eggs shrink or shells weaken, the ration is inadequate.

The fifth stage is late lay, from about 55 weeks onward. Production declines further, and feed cost per dozen rises. This is the stage where producers must make a decision: continue feeding the current flock, force a molt, or replace with pullets. The decision depends on feed prices, egg prices, and the cost of replacement pullets. As a rule of thumb, if feed cost per dozen exceeds the egg price minus other costs, it is time to cull or molt.

The sixth stage is molt, if you choose to force one. A forced molt typically lasts 2 to 4 weeks with restricted feed or a low-calcium ration. Feed intake drops dramatically during the molt, which actually reduces feed costs temporarily. After molt, hens return to production and eat at levels similar to peak lay. The molt extends the productive life of the flock but adds a period of zero egg revenue. Your budget must account for this.

Common Mistakes in Layer Feed Budgeting

Many flock owners make the same errors when budgeting feed, and these errors cost real money. Recognizing them in your own operation is the first step to fixing them.

The most common mistake is using a single average feed intake for the entire year. Feed intake varies by season, production stage, and temperature. A budget built on one number will be wrong most of the year. The fix is to build a monthly budget that adjusts for expected weather and production changes.

The second mistake is ignoring waste. Feed that ends up on the floor is still a cost, but it does not produce eggs. Waste of 5 to 10 percent is common with poorly adjusted feeders or overfilled tubes. The fix is to measure feed disappearance, not just what you think the birds ate. If you buy 1,000 pounds of feed and the birds should eat 900 pounds, the missing 100 pounds is waste, theft, or spoilage. Find it.

The third mistake is comparing feed prices per pound instead of cost per hen per day. A feed that costs $0.26 per pound but has higher energy density may cost less per hen per day than a feed at $0.24 per pound with lower energy. Always calculate cost per hen per day and cost per dozen eggs, not cost per bag.

The fourth mistake is failing to adjust for temperature. A flock in an unheated barn in January eats 30 to 45 percent more than the same flock in May. Producers who do not budget for this either run out of feed or watch hens lose condition. The fix is to apply the 1 percent per degree rule to your intake estimates.

The fifth mistake is not tracking actual feed usage against the budget. A budget is only useful if you compare it to reality. If you budget 650 pounds per week but actually use 700, you have a problem that will cost you money all year. Weekly tracking catches this early.

The sixth mistake is holding too much feed and letting it spoil. Feed is perishable. A 6-month supply stored in a damp barn will mold, and moldy feed reduces intake and can sicken birds. The fix is to store no more than 6 weeks of feed unless you have excellent dry storage and a rotation system.

The seventh mistake is ignoring the cost of feed per dozen eggs as the flock ages. Many producers keep feeding a flock at the same rate long after production has declined, and they wonder why profits shrink. The fix is to recalculate feed cost per dozen monthly and use it as a trigger for culling or molting decisions.

Monitoring and Recordkeeping for Feed Management

You cannot manage what you do not measure. A simple recordkeeping system for feed and egg production is the backbone of a working feed budget. The system does not need to be elaborate. A notebook or a spreadsheet is sufficient. What matters is consistency and using the data to make decisions.

Keep a daily egg production record. Count eggs collected each day and divide by the number of hens in the flock to get daily production percentage. This number feeds directly into your feed cost per dozen calculation. Without it, you are guessing at the most important output measure.

Keep a weekly feed usage record. Weigh feed added to feeders and subtract what remains at the end of the week. Divide by the number of hens to get weekly average daily intake. Compare this to your budget. If actual intake is consistently above or below budget by more than 5 percent, investigate and adjust.

Keep a feed purchase and inventory log. Record the date, quantity, and price of every feed purchase. Track inventory on hand. This gives you two things: a record of actual feed costs and an early warning when inventory is running low. It also lets you compare prices between suppliers and decide when to buy ahead.

Keep a body weight record. Weigh a sample of 10 to 20 birds monthly. Body weight is the best single indicator of whether hens are getting enough feed. If weights are falling, intake is inadequate or disease is present. If weights are rising excessively, intake is too high or the ration is too energy-dense.

Keep a mortality and culling record. Dead and culled birds eat no feed, so your flock count must be accurate for intake calculations. A flock that starts the month at 200 hens and ends at 190 has lower total feed needs than the starting count suggests. Update your budget when you remove birds.

Review your records monthly. Calculate feed cost per dozen eggs, compare actual feed usage to budget, and check body weights and production trends. Use this review to decide whether to continue the current feeding program, adjust rations, purchase feed ahead, or make culling decisions. The monthly review is where budgeting becomes management.

When to Call a Veterinarian or Extension Agent

Feed budgeting is a management tool, but sudden changes in feed intake or egg production can signal a health problem that requires professional help. Knowing when to stop managing and start calling is important for flock health and your bottom line.

Call your veterinarian if feed intake drops by more than 10 percent over 3 consecutive days without an obvious cause such as heat stress or a ration change. A sudden refusal to eat can indicate disease, poor feed quality, or a toxin in the feed. If the feed looks or smells abnormal, stop feeding it and contact your veterinarian or extension agent immediately.

Call if water consumption changes suddenly. Hens drink about 2 parts water to 1 part feed. If water intake drops, feed intake will follow within hours. Sudden increases in water consumption can indicate kidney problems, certain diseases, or dietary issues. Both directions warrant investigation.

Call if egg production drops sharply. A sudden drop of more than 5 percent in a day, or a decline that continues over several days, can indicate infectious disease, a management failure, or a nutritional problem. Production drops can also be caused by stress, such as a predator attack, a sudden feed change, or extreme weather. Your veterinarian or extension agent can help you distinguish a management problem from a disease outbreak.

Call if you see signs of illness in the flock. Reduced feed intake is often the first sign of disease, but it is usually accompanied by other signs: lethargy, decreased activity, ruffled feathers, respiratory signs, diarrhea, or sudden death. Any of these warrant a veterinary call.

Call if you suspect a feed quality problem. Moldy feed, feed with an unusual odor, or feed that has been contaminated by rodents or insects can cause illness. Your extension agent can help you test feed and identify the problem. If you suspect mycotoxins, a feed test is essential because some toxins cause production losses at levels too low to detect by smell or sight.

Call your extension agent for help with ration formulation, feed budgeting, or economic decisions. Extension agents have access to current feed price data, ration calculators, and research on feeding programs. They can help you evaluate whether a feed price is competitive, whether a ration meets your flock's needs, and whether your feeding program is cost-effective. This is a free resource that many producers underuse.

For reportable diseases, contact your veterinarian or state animal health official immediately. Avian influenza and Newcastle disease are reportable in many jurisdictions, and any suspicion of these diseases requires prompt notification. Delayed reporting can spread disease and trigger regulatory action. The USDA APHIS poultry health program and the World Organisation for Animal Health provide guidance on notifiable poultry diseases.

Frequently Asked Questions

How much feed does a laying hen eat per day?

A standard laying hen eats 0.25 to 0.35 pounds of feed per day, with 0.30 pounds as a good planning baseline. Lighter White Leghorn-type hens eat less, around 0.22 to 0.25 pounds. Heavier brown egg layers eat more, around 0.28 to 0.35 pounds. Intake rises in cold weather by about 1 percent per degree below 65 degrees Fahrenheit and falls in hot weather. Measure your own flock to get an accurate number.

How do I calculate feed cost per dozen eggs?

Use this formula: daily feed intake per hen in pounds multiplied by feed price per pound, multiplied by 12, divided by eggs per hen per day. For example, a hen eating 0.30 pounds per day with feed at $0.25 per pound and laying at 85 percent production has a feed cost of (0.30 x $0.25 x 12) / 0.85 = $1.06 per dozen. As production declines, feed cost per dozen rises even if feed price and intake stay the same.

What is a good feed conversion ratio for layers?

A good feed conversion for layers is 1.8 to 2.2 pounds of feed per dozen eggs for brown egg strains and 1.7 to 2.0 pounds for white egg strains. This means the flock eats about 2 pounds of feed for every dozen eggs produced. If your conversion is above 2.2 pounds per dozen, look for waste, cold stress, low feed quality, or excessive body weight. If it is below 1.7, verify your measurements.

How much feed should I keep on hand?

Keep a minimum of 2 weeks of feed on hand, and preferably 4 to 6 weeks if you depend on a single feed mill or face seasonal delivery challenges. Multiply your daily feed usage by 14 for a 2-week supply or by 28 to 42 for a 4 to 6 week supply. Store feed in a dry, rodent-proof area and rotate stock so the oldest feed is used first.

How does cold weather affect feed costs?

Cold weather increases feed intake because hens burn extra calories to maintain body temperature. Feed intake rises about 1 percent for each degree Fahrenheit below 65 degrees. At 35 degrees, a hen needs roughly 30 percent more feed than at 70 degrees. This can add 20 to 30 percent to your winter feed bill. Budget for this increase or you will run out of feed mid-winter.

When should I cull or molt my flock based on feed costs?

Cull or molt when feed cost per dozen eggs exceeds the egg price minus your other costs per dozen. Recalculate feed cost per dozen monthly as the flock ages. Many producers use a threshold of 2.2 to 2.5 pounds of feed per dozen as a trigger for action. If production has fallen below 50 to 60 percent and feed costs are high, replacement pullets or a forced molt may be more economical than continuing the current flock.

Should I buy cheaper feed to save money?

Not necessarily. Compare feed on cost per hen per day, not cost per bag. A cheaper feed with lower energy density may require hens to eat more to meet their energy needs, which can make it more expensive per hen per day. Calculate cost per dozen eggs for each feed option. Also consider feed quality. Poor quality feed can reduce production, egg size, and shell quality, which costs more than the feed savings.

What records should I keep for feed management?

Keep daily egg production counts, weekly feed usage weights, a feed purchase and inventory log, monthly body weights of a sample of birds, and a mortality and culling record. Review these monthly to calculate feed cost per dozen eggs, compare actual feed usage to budget, and make feeding and culling decisions. A simple spreadsheet is sufficient for most operations.
