Feed Storage and Delivery Systems for Layer Farms

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

Key Takeaways

Feed storage capacity should be sized for 7 to 14 days of consumption to balance feed freshness against delivery frequency, with a 10,000-bird flock requiring 7-8 tons for 7 days.
Bin materials like galvanized steel or food-grade polypropylene are recommended, featuring smooth interiors and a minimum 60-degree hopper angle to ensure proper feed flow and prevent bridging.
Regular bin cleaning, including emptying before each delivery and deep cleaning twice annually, is crucial to prevent mold, mycotoxin contamination, and pest infestations.
Auger systems require sizing for 4-6 tons per hour capacity, matched to feed line length and bird density, with weekly calibration of delivery rates essential for uniform nutrient intake.
Proactive pest control measures, such as rodent-proof bins with screened vents and maintaining a clean perimeter, are vital to prevent feed contamination and disease transmission.

Feed represents the single largest recurring cost on a commercial layer farm, often accounting for 60 to 70 percent of total production expenses. The way you store and deliver that feed affects not only your bottom line but also bird health, egg quality, and flock uniformity. Poor storage leads to spoilage, mycotoxin contamination, and pest infestations. Faulty delivery systems cause uneven nutrient intake, with some birds overeating and others being underfed. This guide covers feed storage for layer farms from bin selection and placement to auger systems, hygiene protocols, and monitoring practices. It is written for farm owners, production managers, and farm employees who plan new facilities or want to improve existing feed handling operations.

Feed Storage for Layer Farms: Planning Your System

Feed storage for layer farms is not an afterthought. It is a core infrastructure decision that affects daily labor, feed quality, biosecurity, and bird performance. Before you purchase bins or install augers, you need to answer several planning questions that shape the entire system.

Determine Your Feed Storage Capacity

The first planning step is calculating how much feed storage you need. This depends on your flock size, daily consumption, and how often you want to receive feed deliveries. A standard commercial layer consumes approximately 100 to 110 grams of feed per day, though this varies with breed, age, temperature, and production stage. A flock of 10,000 hens at peak production will eat roughly 1,000 to 1,100 kilograms per day, or about 2,200 to 2,400 pounds.

Most layer farms operate with a storage capacity of 7 to 14 days of feed consumption. This range balances several factors. Smaller storage means more frequent deliveries, which increases the risk of running out during weather delays or supply chain disruptions. Larger storage reduces delivery frequency but increases the time feed sits in the bin, which raises the risk of spoilage, nutrient degradation, and pest infestation.

For a 10,000 bird flock, a 7 day supply requires about 7 to 8 tons of storage capacity. A 14 day supply requires 14 to 16 tons. Most farms install two or more bins to allow one bin to be emptied completely before the next delivery arrives. This practice helps prevent the buildup of old feed at the bottom of the bin.

Assess Your Delivery Access

Your feed supplier needs to access your bins with a bulk truck. The truck must be able to maneuver close enough for the auger to reach the fill port on top of the bin. Plan a driveway or access lane that is at least 12 feet wide with a turning radius of at least 40 feet. The area around the bins must be level and firm enough to support a loaded truck, which can weigh 40,000 to 80,000 pounds.

Consider the location of your bins relative to the feed mill and your delivery schedule. If you are in a region with heavy snowfall or frequent rain, you need an access route that remains passable year round. Some farms install a concrete apron around the bins to provide a stable surface for the delivery truck and to simplify cleanup of spilled feed.

Plan for Future Expansion

Feed storage for layer farms should account for potential flock expansion. If you plan to add birds in the coming years, install bins that can handle the larger capacity now rather than replacing them later. The cost difference between a 10 ton bin and a 15 ton bin is often modest compared with the cost of site preparation and installation. You can also plan the bin pad to accommodate additional bins later, leaving space and proper spacing for future units.

Feed Bin Design and Selection

The feed bin is the central component of your storage system. Its design determines how well feed flows, how easily it can be cleaned, and how long it lasts. Selecting the right bin requires attention to material, shape, size, and features.

Bin Materials

Two materials dominate the market for layer farm feed bins: galvanized steel and food grade polypropylene.

Galvanized steel bins are the traditional choice. They are strong, durable, and resistant to damage from weather and impact. A quality galvanized bin with proper maintenance can last 20 years or more. The main drawback is that steel can corrode in humid environments, especially where condensation forms on the interior surface. Galvanized bins also conduct heat, which can cause temperature swings inside the bin that promote condensation and spoilage.

Food grade polypropylene bins have become increasingly popular in recent years. They are lighter, easier to clean, and resistant to corrosion. The smooth interior surface reduces feed buildup and makes sanitation easier. Polypropylene does not conduct heat as readily as steel, which helps moderate temperature fluctuations. The main drawback is that polypropylene can be damaged by impact and may have a shorter lifespan than quality steel.

Some farms use bins made from other materials, including fiberglass and stainless steel. These are less common due to higher cost, but they offer excellent corrosion resistance and cleanability for farms with special requirements.

Bin Shape and Hopper Angle

The shape of the bin, particularly the hopper at the bottom, determines how feed flows out. A bin with a shallow hopper angle will leave a significant amount of feed stuck at the bottom, which becomes stale and can harbor pests and mold. The hopper angle should be at least 60 degrees from horizontal, and 65 to 70 degrees is better for most feed types.

The bin outlet should be large enough to prevent bridging, which occurs when feed forms an arch over the outlet and stops flowing. Feed with high moisture content, fine particles, or added fats is more prone to bridging. A bin outlet of at least 8 to 10 inches in diameter is recommended for standard layer feed. Some bins include aeration devices or vibrators to help maintain flow, but these add cost and require maintenance.

Bin Size and Configuration

Feed bins for layer farms typically range from 4 to 30 tons of capacity. The size you need depends on your flock size and delivery frequency, as calculated earlier. Most layer farms use multiple bins, either side by side or in a row, to provide flexibility and backup capacity.

When configuring multiple bins, consider how feed will be routed from each bin to the feed lines. A common arrangement is to place bins at one end of the layer house, with an auger system that carries feed down the length of the house. Another arrangement places bins in the center of the house, with feed lines running in both directions. The center placement reduces the distance feed must travel and can simplify the auger system.

Bin Features to Consider

Modern feed bins offer a range of features that improve function and safety. A fill pipe with a cap prevents rain and debris from entering the bin during delivery. A level indicator, either mechanical or electronic, tells you when the bin is full and helps you monitor feed usage. A manhole or access hatch on the top allows inspection and cleaning. Some bins include a ladder and safety cage for safe access to the top.

Ventilation is a critical feature. A bin must breathe to prevent condensation and pressure buildup. Look for bins with screened vents that allow air exchange while keeping out birds and insects. The vent should be positioned to prevent rain from entering.

Bin Placement and Installation

Where you place your feed bins affects feed quality, biosecurity, and daily operations. Proper placement and installation are as important as the bin itself.

Site Selection

Choose a bin location that is close to the layer house to minimize the distance feed must travel through the auger system. Longer distances require larger augers and more power, increasing both initial and operating costs. However, the bins should not be so close that they interfere with house ventilation, access doors, or equipment maintenance.

The bins should be placed on a concrete pad that extends at least 2 feet beyond the bin footprint on all sides. The pad provides a stable base, prevents the bin from settling, and makes it easier to clean up spilled feed. The pad should have a slight slope away from the bin to promote drainage, and the surrounding area should be graded so water does not pool near the base.

Keep bins away from trees, which drop leaves and branches that can damage the bin or attract pests. Also avoid placing bins near other buildings where wild birds roost or where rodents may nest. If possible, position the bins so the fill port faces the delivery truck access, minimizing the length of the fill auger needed.

Foundation Requirements

A feed bin full of feed is heavy. A 10 ton bin holds 20,000 pounds of feed, plus the weight of the bin itself. The foundation must support this load without settling or shifting. For most soils, a reinforced concrete pad 4 to 6 inches thick with proper footings is sufficient. In areas with poor soil or high water tables, you may need deeper footings or a more substantial foundation.

The bin legs must be bolted to anchor plates embedded in the concrete. These anchors prevent the bin from tipping in high winds. Check the anchor bolts periodically and retighten them if they loosen.

Installation Considerations

Bin installation is typically done by the manufacturer or a qualified dealer. The bin sections are lifted into place with a crane and bolted together. This is not a do it yourself job, as improper assembly can lead to structural failure, leaks, or feed flow problems.

After installation, have the installer test the bin by filling it partially and checking for leaks, proper flow, and correct operation of the level indicator. Take photographs of the installed bins and keep the manufacturer documentation, including warranty information and maintenance instructions.

Feed Delivery Systems for Poultry: Auger Systems

The feed delivery system moves feed from the bin to the birds. The most common system on layer farms is the auger system, which uses a rotating screw inside a tube to convey feed along the length of the house. Understanding how these systems work helps you operate them effectively and troubleshoot problems.

How Auger Systems Work

An auger system consists of a drive unit, a tube or pipe, and a screw shaped auger inside the tube. The drive unit turns the auger, which moves feed along the tube. Feed drops into the tube through an inlet from the bin, travels along the length of the auger, and is deposited into feed pans or troughs at intervals along the line.

The feed line is typically suspended from the ceiling or supported on stands above the cages. As the auger turns, feed is pushed along the tube and drops through openings into the feed pans below. The system runs on a timer or a sensor that detects when the feed level in the pans is low.

Components of a Feed Delivery System

A complete feed delivery system for poultry includes several components beyond the auger itself. The drive unit, usually an electric motor with a gearbox, provides the power to turn the auger. The motor size depends on the length of the feed line and the amount of feed to be moved.

The feed line tube is typically made of galvanized steel or PVC. The tube diameter ranges from 2 to 4 inches, with larger diameters used for longer lines and higher capacities. The auger flights are designed to move feed efficiently without grinding it or causing separation of ingredients.

Drop tubes or feed pans are positioned along the feed line at regular intervals. The spacing depends on the cage system and the number of birds per cage. A typical arrangement provides one feed pan for every 6 to 10 birds, with pans spaced 12 to 18 inches apart.

The control system regulates when the auger runs. A simple timer can be set to run the auger for specific intervals throughout the day. More advanced systems use sensors that detect when feed levels are low and activate the auger only when needed. Some systems include a weigh scale that measures feed usage and can be integrated with farm management software.

Auger Sizing and Capacity

The auger system must be sized to deliver enough feed to all birds within a reasonable time. The capacity of an auger system depends on the auger diameter, the speed of rotation, and the length of the line. As a general guide, a 2 inch auger can deliver 1 to 2 tons per hour, while a 3 inch auger can deliver 3 to 4 tons per hour.

To calculate the required capacity, divide your daily feed usage by the number of hours you want the system to run each day. For example, a 10,000 bird flock consuming 1,100 kilograms per day, with the system running 6 hours per day, requires a capacity of about 183 kilograms per hour. This is well within the capability of a 2 inch auger.

However, the system must also handle peak demand. Feed intake is not uniform throughout the day. Birds eat heavily in the morning and again in the afternoon, with reduced intake during the middle of the day and at night. The system should be able to fill all feed pans within 30 to 60 minutes to ensure all birds have access to feed at the same time.

Alternative Feed Delivery Systems

While auger systems are the most common, other feed delivery systems for poultry exist. Chain and flight conveyors use a moving chain with attached flights to drag feed along a trough. These systems are simpler and lower cost but are less efficient and harder to clean than augers.

Pan feeder systems use a central hopper that distributes feed to pans through a system of tubes and drop pipes. These are more common in broiler operations but are used in some layer houses, particularly those with floor systems rather than cages.

For small farms, manual feed delivery using wheelbarrows or carts may be practical. This approach eliminates the capital cost of an auger system but requires significant labor and is not practical for flocks larger than a few hundred birds.

Feed Delivery System Layout and Design

The layout of your feed delivery system affects how evenly birds receive feed and how efficiently the system operates. Proper design considers the length of the feed lines, the number of birds per pan, and the arrangement of bins and augers.

Single Line vs Multiple Lines

Layer houses typically have feed lines running the length of the house, with one line serving each row of cages. A house with four cage rows needs four feed lines. Each line has its own auger and drive unit, or a single drive unit can power multiple lines through a system of gears and shafts.

Multiple lines from a single drive unit reduce motor costs but complicate the system. If one line jams, the entire system stops. Individual drive units for each line allow independent operation, which is helpful during maintenance or if one line needs to be run more than others.

Feed Line Length and Auger Selection

The maximum length of a feed line depends on the auger diameter and the drive unit power. A 2 inch auger can typically move feed 200 to 300 feet, while a 3 inch auger can handle 400 feet or more. If your house is longer, you may need to place bins in the center and run lines in both directions, or use a larger auger.

Longer feed lines require more power and create more wear on the auger and tube. The auger must be supported at intervals to prevent sagging, and the tube must be properly aligned to prevent binding. Consult with your equipment supplier to determine the appropriate auger size and drive unit for your specific house dimensions.

Feed Pan Spacing and Bird Access

The spacing of feed pans along the line determines how many birds share each pan. Overcrowding at the feeder causes stress and uneven feed intake, with dominant birds eating first and timid birds getting less. The recommended spacing depends on the cage configuration.

For conventional cage systems, provide at least 4 inches of feeder space per bird. A feed pan with a 12 inch diameter provides approximately 37 inches of feeder space around its circumference, so it can serve 8 to 9 birds. For colony cages and floor systems, provide at least 1.5 to 2 inches of feeder space per bird at the trough.

Elevation and Leveling

The feed line must be level along its entire length to ensure even feed distribution. If the line slopes, feed will accumulate at the low end and the high end will be underfilled. Check the level of the feed line regularly, especially after any changes to the house structure or equipment.

The height of the feed line should match the cage system. Feed pans should be positioned so birds can eat comfortably without straining or reaching. The height may need adjustment as birds age and the cage system settles.

Feed Storage Hygiene and Pest Control

Feed storage hygiene is critical for bird health and egg quality. Contaminated feed can introduce diseases, toxins, and pests that affect the entire flock. A systematic approach to hygiene prevents most problems.

Common Feed Contaminants

Mold is the most common contaminant in stored feed. Mold grows when feed moisture exceeds 13 to 14 percent and temperatures are warm. Mold not only reduces the nutritional value of feed but can produce mycotoxins, which are toxic compounds that cause a range of health problems in layers, including reduced egg production, liver damage, and immunosuppression.

Bacteria can also contaminate feed, particularly Salmonella species. Feed is a known vehicle for Salmonella transmission in poultry flocks. Good storage hygiene reduces the risk of bacterial contamination, though it cannot eliminate it entirely.

Pests are both a contaminant and a cause of contamination. Rodents, wild birds, and insects consume feed, leave droppings, and carry diseases. A single mouse can consume 3 grams of feed per day and contaminate far more with its droppings and urine.

Bin Cleaning Procedures

Clean bins before each feed delivery, and perform a deep clean at least twice per year. The cleaning procedure depends on whether the bin is empty or has residual feed.

For routine cleaning, empty the bin completely before the delivery truck arrives. Sweep or vacuum out any residual feed, paying special attention to the corners and the hopper area. Inspect the bin interior for signs of mold, moisture, or pest activity. Wipe down the interior surfaces with a dry cloth or brush to remove dust and fine particles.

For deep cleaning, empty the bin and remove any residual feed. Use a food safe cleaner and warm water to wash the interior surfaces. Rinse thoroughly and allow the bin to dry completely before adding new feed. Inspect the bin for damage, rust, or worn seals that could allow moisture or pests to enter.

Some farms use fumigation or fogging to disinfect bins, but these treatments must be done carefully and only with products approved for use in feed storage areas. Always follow the product label instructions and ensure the bin is completely dry and free of chemical residue before adding feed.

Pest Prevention Measures

Preventing pests from entering your feed storage area is easier than dealing with an infestation. The bin itself should be rodent proof, with no openings larger than 1/4 inch. The fill pipe cap should fit tightly, and the vents should be screened with hardware cloth.

The area around the bins should be kept clean and free of vegetation. Trim grass and weeds within a 3 foot radius of the bin pad. Remove any debris or equipment that could provide harborage for rodents. Keep the bin pad swept so spilled feed does not accumulate.

Establish a regular pest monitoring program. Check for rodent droppings, gnaw marks, and burrows around the bin pad. Look for signs of insect infestation in and around the bins. If you find evidence of pests, take corrective action immediately. This may include trapping, baiting, or calling a professional pest control service.

Feed Spoilage Prevention

Feed spoilage is not always visible. The feed may look normal but have reduced nutritional value or contain toxins. The key to preventing spoilage is controlling moisture and temperature.

Keep bins sealed and protected from rain. Check the fill pipe cap and the bin roof for leaks after heavy rain. Inspect the bin interior for condensation, which can occur when warm moist air enters a cool bin. Condensation is most common in spring and fall when temperatures fluctuate dramatically.

Do not store feed longer than necessary. A 7 to 14 day supply is ideal. Feed that sits for weeks or months is more likely to spoil, even under good storage conditions. Rotate feed stock so older feed is used first.

Monitor feed temperature. Feed that heats up in the bin indicates microbial activity, which spoils the feed and produces toxins. If you notice feed heating, empty the bin and inspect the feed for mold or off odors.

Feed Delivery System Maintenance

A feed delivery system operates in a harsh environment. Dust, feed particles, and moisture combine to cause wear and corrosion. Regular maintenance prevents breakdowns and ensures consistent feed delivery.

Daily Checks

Perform a visual inspection of the feed delivery system each day. Look for feed spills, which indicate a leak or misalignment. Listen for unusual noises from the drive unit or auger, which may indicate a bearing failure or a foreign object in the line. Check that all feed pans have feed and that the feed level is consistent across the line.

Weekly Maintenance

Each week, check the drive unit for proper oil levels and signs of overheating. Inspect the auger tube for wear, especially at bends and connections. Check the drop tubes and feed pans for damage or blockage. Clean any feed buildup around the drive unit and along the tube.

Lubricate moving parts according to the manufacturer recommendations. Use only food grade lubricants on components that could contact feed. Over lubrication can attract dust and create a mess, so apply lubricant sparingly.

Monthly Maintenance

Each month, perform a more thorough inspection of the feed delivery system. Check the auger for wear, measuring the flight thickness if possible. A worn auger moves less feed and may need to be replaced. Inspect the tube for holes or wear, especially at the bottom where feed abrasion is greatest.

Check all electrical connections and wiring. Look for loose connections, frayed wires, or signs of overheating. Test the control system, including timers, sensors, and alarms. Verify that the emergency stop function works properly.

Seasonal Maintenance

At the start of each season, perform maintenance appropriate to the weather conditions. Before winter, check that the drive unit and controls are protected from moisture and cold. Some systems need winter grade lubricants. Before summer, check that ventilation around the drive unit is adequate to prevent overheating.

After any major weather event, inspect the bins and feed delivery system for damage. High winds can shift bins or damage fill pipes. Heavy rain can cause leaks or flooding around the bin pad.

Common Mistakes in Feed Storage and Delivery

Even experienced farmers make mistakes in feed storage and delivery. Knowing the most common errors helps you avoid them.

Oversizing or Undersizing Storage

Installing bins that are too large for your operation leads to feed sitting for extended periods, increasing spoilage risk. Bins that are too small require frequent deliveries, increasing the risk of running out and the cost per ton of delivered feed. Match your storage capacity to your actual feed consumption and delivery schedule.

Ignoring Bin Hygiene

Feed bins are out of sight and often out of mind. Many farmers rarely inspect or clean their bins, allowing mold and pests to build up over time. Make bin inspection and cleaning a scheduled task, not an afterthought.

Running Augers Too Long or Too Short

Auger systems that run too long overfill feed pans, causing feed to spill and be wasted. Systems that run too short leave some birds without feed. Calibrate your system to match the actual feed consumption of your flock, and adjust the run time as the flock ages and feed intake changes.

Using Poor Quality Feed Ingredients

No storage system can compensate for poor quality feed. Feed that arrives with high moisture, fine particles, or contaminants will cause problems regardless of how well you store it. Work with a reputable feed supplier and inspect deliveries for quality.

Neglecting Pest Control

Rodents and wild birds are persistent problems around feed storage areas. A single rat can consume and contaminate a surprising amount of feed. Establish a year round pest control program, not just a response when you see a problem.

Failing to Calibrate

Feed delivery systems drift over time. Augers wear, drive units lose efficiency, and feed formulations change. Without regular calibration, your system may deliver more or less feed than you think. Calibrate at least weekly and after any equipment adjustment.

Monitoring and Recordkeeping for Feed Systems

Accurate monitoring and recordkeeping help you identify problems early and make informed management decisions. Feed records are also useful for calculating production costs and evaluating flock performance.

Feed Intake Monitoring

Track daily feed consumption for each house or flock. This is typically done by weighing feed as it is delivered to the bins and subtracting the weight of feed remaining at the end of the period. Some farms use load cells on the bins to measure feed weight continuously.

Compare actual feed consumption to expected consumption based on the flock age, breed, and production stage. A sudden drop in feed intake is often the first sign of disease, heat stress, or a feed quality problem. A sudden increase in feed intake may indicate a feed formulation error or a problem with the delivery system.

Feed Quality Monitoring

Inspect feed deliveries for quality. Check the moisture content if possible, and look for signs of mold, insects, or foreign material. Keep a sample of each feed delivery in a sealed container for reference. If you suspect a feed quality problem, the sample can be sent to a laboratory for analysis.

Monitor feed in the bins for signs of spoilage. Check the temperature of the feed at the bin outlet. Feed that is warm to the touch may be heating, which indicates microbial activity.

Equipment Performance Records

Keep a log of equipment maintenance and repairs. Record the date, the work performed, and any parts replaced. This log helps you identify patterns of wear and plan preventive maintenance. It also provides documentation if you need to make a warranty claim.

Record any equipment failures and the corrective action taken. If the same problem occurs repeatedly, it may indicate a design flaw or a need for a different approach.

Flock Performance Records

Feed intake is closely tied to flock performance. Track egg production, egg weight, feed conversion ratio, and mortality alongside feed intake. A change in any of these parameters may indicate a feed related problem.

The feed conversion ratio, calculated as feed consumed divided by egg mass produced, is a key indicator of feed efficiency. If the feed conversion ratio worsens, investigate the cause. It may be a feed quality issue, a delivery system problem, or a health issue in the flock.

Troubleshooting Feed Storage and Delivery Problems

When problems arise, a systematic approach to troubleshooting saves time and reduces losses. Work through the possible causes from the most likely to the least likely.

Feed Not Flowing from the Bin

If feed is not flowing from the bin, check the obvious causes first. The bin may be empty, even if the level indicator suggests otherwise. The outlet may be blocked by a bridge of feed or a foreign object. The auger may be jammed or the drive unit may not be running.

If the bin has feed and the outlet appears clear, check for bridging. Bridging occurs when feed forms an arch over the outlet. It is more common with fine or moist feed. Tap the bin gently to break the bridge, or use a rod to poke the feed from above. Do not put your hand into the bin while it is running.

Uneven Feed Distribution

If some feed pans receive more feed than others, the problem is likely in the auger system. Check that the auger is not worn or bent. Check that the drop tubes are clear and properly positioned. Check that the feed line is level along its entire length.

If the problem is consistent, the feed line may need re leveling or the drop tube positions may need adjustment. If the problem is intermittent, there may be a foreign object in the auger or a drive unit problem.

Feed Wastage

Feed wastage is a common and costly problem. Look for feed on the floor beneath the feed pans and along the feed line. This may indicate overfilled pans, misaligned pans, or a system that runs too long.

Check the feed pan design. Some pans have a grill or grid that prevents birds from flicking feed out. If your pans lack this feature, consider retrofitting them. Adjust the feed level in the pans to the recommended height, which is typically about half full.

Moldy or Spoiled Feed

If you find mold in the feed, the problem is moisture. Check the bin for leaks, especially around the fill pipe cap and the roof seams. Check for condensation on the interior surfaces. Check that the vents are not blocked.

If the feed is spoiled, empty the bin and clean it thoroughly before refilling. Do not feed spoiled feed to the birds, as it may contain mycotoxins that can cause serious health problems.

When to Call a Veterinarian or Extension Agent

Most feed storage and delivery problems are mechanical and can be solved by farm staff. However, some situations require professional help.

Signs of Mycotoxin Poisoning

If your flock shows signs of mycotoxin poisoning, call a veterinarian immediately. Symptoms include reduced feed intake, decreased egg production, poor eggshell quality, diarrhea, and increased mortality. Mycotoxins can also cause immunosuppression, making birds more susceptible to other diseases.

A veterinarian can help diagnose the problem and recommend treatment. This may include removing the contaminated feed, adding a mycotoxin binder to the diet, and providing supportive care. An extension agent can help you test your feed and identify the source of contamination.

Unexplained Drop in Feed Intake

A sudden drop in feed intake of more than 10 percent, without an obvious cause such as heat stress or a feed delivery problem, warrants a call to your veterinarian. Reduced feed intake is a common early sign of many diseases, including avian influenza and Newcastle disease.

Your veterinarian can examine the flock, run diagnostic tests, and recommend appropriate action. If the cause is infectious, you may need to report the finding to the relevant animal health authority.

Feed Related Disease Outbreaks

If you suspect that feed is the source of a disease outbreak, contact your veterinarian and your extension agent. This is particularly important for Salmonella, which can be transmitted through feed and has public health implications.

Your extension agent can help you trace the feed back to the supplier and arrange for testing of the feed. Your veterinarian can advise on treatment and biosecurity measures to prevent the spread of disease within the flock.

Design and Planning Assistance

If you are planning a new feed storage and delivery system, or making major changes to an existing system, consider consulting with an extension agent or a feed equipment specialist. They can help you size the system correctly, select appropriate equipment, and design a layout that meets your needs.

An extension agent can also provide guidance on feed storage hygiene, pest control, and other management practices. Many extension services offer workshops and publications on these topics.

Frequently Asked Questions

How much feed storage capacity do I need for my layer farm?

Plan for 7 to 14 days of feed consumption. Calculate your daily feed usage by multiplying the number of birds by the average daily feed intake, which is approximately 100 to 110 grams per bird per day for commercial layers. A 10,000 bird flock needs about 1,000 to 1,100 kilograms per day, so a 7 day supply requires 7 to 8 tons of storage. Consider your delivery schedule and the reliability of your feed supplier when choosing between 7 and 14 days of capacity.

What is the best material for a feed bin?

Galvanized steel and food grade polypropylene are the two most common materials. Galvanized steel is durable and long lasting but can corrode in humid conditions and conducts heat. Polypropylene is lighter, easier to clean, and more resistant to corrosion, but may be damaged by impact. Choose based on your climate, budget, and maintenance capabilities. The most important factor is a smooth interior surface that prevents feed buildup and is easy to clean.

How often should I clean my feed bins?

Clean bins before each feed delivery to remove residual feed and prevent buildup. Perform a deep clean at least twice per year, or more often if you have had mold or pest problems. The deep clean involves emptying the bin completely, washing the interior with a food safe cleaner, rinsing thoroughly, and allowing the bin to dry completely before refilling.

How do I know if my auger system is sized correctly?

Your auger system should be able to fill all feed pans within 30 to 60 minutes. Calculate your daily feed usage and divide by the number of hours you want the system to run. A 2 inch auger typically delivers 1 to 2 tons per hour, while a 3 inch auger delivers 3 to 4 tons per hour. If your system cannot fill the pans quickly enough, you may need a larger auger or a more powerful drive unit.

What causes feed to bridge in the bin?

Bridging occurs when feed forms an arch over the bin outlet and stops flowing. It is more common with feed that has high moisture content, fine particles, or added fats. A hopper angle of at least 60 degrees helps prevent bridging, as does a bin outlet of at least 8 to 10 inches. If bridging is a persistent problem, consider a bin with aeration devices or a vibrator to help maintain flow.

How can I prevent mold in my feed bins?

Control moisture and temperature. Keep bins sealed and protected from rain, and check for condensation regularly. Use feed within 7 to 14 days of delivery, and rotate stock so older feed is used first. Clean bins regularly to remove residual feed that can harbor mold spores. If you find mold, empty the bin, clean it thoroughly, and investigate the source of moisture.

What should I do if I suspect mycotoxin contamination in my feed?

Remove the suspect feed from the system and contact your veterinarian immediately. Mycotoxins can cause reduced feed intake, decreased egg production, poor eggshell quality, and increased mortality. Your veterinarian can help diagnose the problem and recommend treatment, which may include adding a mycotoxin binder to the diet. An extension agent can help you test the feed and identify the source of contamination.

How do I calibrate my feed delivery system?

Weigh the feed delivered to a known number of feed pans over a set time period, then adjust the run time to match your flock's feed consumption. Repeat the calibration weekly and after any equipment adjustment or feed formula change. Keep records of the calibration results to track changes over time and identify when the system needs maintenance.
