Broiler House Orientation and Site Selection

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

Key Takeaways

Ventilation System Specific Orientation: Naturally ventilated houses should orient their ridge east-west to maximize summer breeze capture on north-south sidewalls and minimize afternoon solar gain. Tunnel ventilated houses require the air inlet end to face the prevailing summer wind to reduce static pressure and fan energy consumption, avoiding placement towards winter winds or existing odor sources.
Topographical and Drainage Imperatives: Sites should be selected on the highest practical ground with a 1-3% slope for optimal surface water drainage, avoiding low spots, frost pockets, and flood plains to prevent foundation issues, litter moisture problems, and disease vector proliferation.
Biosecurity and Disease Mitigation Distances: Minimum separation of 50-100 feet between houses on the same farm and 500+ feet between farms is critical to mitigate airborne disease transmission, particularly for pathogens like avian influenza, and to manage odor intrusion.
Solar Heat Load Management: Orienting houses to minimize direct afternoon sun exposure on west-facing walls, especially the brood end, is crucial. Utilizing light-colored reflective roofing and adequate ceiling insulation (R19-R30 in temperate regions) further reduces thermal stress on birds.
Infrastructure and Regulatory Compliance: Adequate all-weather access roads (minimum 12 feet wide) for service vehicles, reliable three-phase power with automatic backup generation, and sufficient water supply (minimum 10 GPM flow rate with quality testing) are essential. Strict adherence to local zoning, setback, and environmental regulations is mandatory.

Choosing where to build a broiler house and which direction it faces are two of the most important decisions you will make as a poultry farmer. These choices affect ventilation, heating costs, litter moisture, bird health, and daily management for the life of the building, which is typically 20 years or more. Getting the orientation wrong is difficult and expensive to fix after the concrete is poured and the equipment is installed.

This guide covers the full planning process for siting and orienting a broiler house. It is written for commercial broiler growers, small flock owners scaling up to their first tunnel ventilated barn, farm planners, and agricultural students. You will learn how prevailing winds, solar path, topography, drainage, and biosecurity shape the best placement for your house. You will also get step by step instructions for laying out the site, common mistakes to avoid, and the records you should keep during planning and construction.

At a Glance

Orient the ridge of a naturally ventilated broiler house east to west so the sidewalls face north and south, capturing prevailing summer breezes and reducing afternoon sun load.
For tunnel ventilated houses, orient the air inlet end toward the prevailing summer wind to reduce static pressure and fan energy use.
Never place the air inlet end of a tunnel house toward the prevailing winter wind or toward an existing poultry house, manure storage, or other odor source.
Place the house on the highest practical ground with a slope of 1 to 3 percent for drainage. Avoid low spots, frost pockets, and flood plains.
Keep at least 50 feet between houses on the same farm and 500 feet or more between farms, depending on your local regulations and bird density.
Allow 15 to 25 feet of clear space around the house for equipment access, fire lanes, and future expansion.
Position the service room or office end of the house upwind of the bird area to reduce odor intrusion and improve biosecurity.
Check your local zoning, setback, and environmental regulations before you finalize any site plan.
Test soil drainage before construction. A percolation test and groundwater check are worth the cost.
Keep records of wind data, solar path, soil tests, and construction decisions. These records help you defend your choices and troubleshoot problems later.

Why Orientation Matters for Broiler Performance

Broilers are sensitive to temperature, humidity, and air speed from the day they arrive until the day they ship. The house orientation determines how much solar heat enters the building, how the wind interacts with the inlets and fans, and how well the ventilation system can do its job. A poorly oriented house can cost you in higher fuel bills during brooding, more electricity for fans in summer, wetter litter, and more condemnations at the plant.

The two main ventilation systems used in modern broiler production have different orientation needs. Natural ventilation relies on wind and temperature differences to move air through sidewall curtains or vents. Tunnel ventilation uses large fans at one end of the house to pull air through inlets at the opposite end. Each system interacts with the site differently.

For naturally ventilated houses, the goal is to catch the prevailing summer breeze through the side openings while minimizing direct afternoon sunlight on the walls. The ridge should run east to west in most climates. This places the long sidewalls facing north and south. The north wall gets little direct sun, and the south wall gets sun at a lower angle in summer, which is easier to shade with overhangs or curtains.

For tunnel ventilated houses, the critical factor is the relationship between the inlet end and the prevailing summer wind. You want the inlet end facing the summer wind so the wind helps push air through the house rather than fighting the fans. This reduces static pressure and allows the fans to move more air per unit of electricity. The house can be oriented north to south or east to west, depending on your local wind patterns, as long as the inlet end faces the summer breeze.

Solar heat gain is the second major consideration. A house with its long axis running north to south gets morning sun on one sidewall and afternoon sun on the other. This creates uneven heating and cooling across the width of the house. An east to west ridge orientation means the south wall gets the most sun, and you can manage that with shade cloth, white paint, or roof overhangs. The north wall stays relatively cool and consistent.

Wind direction data is more important than solar path for tunnel houses. You need at least one full year of local wind data, ideally five years, to understand the prevailing patterns. Most agricultural weather stations and airport weather records can give you this information. Look at the summer wind rose, which shows the direction and speed of wind during the months when you will need maximum ventilation.

The Role of Prevailing Winds

Prevailing winds are the directions from which wind most commonly blows during a given season. You need to know these for both summer and winter because they affect ventilation and odor differently.

In summer, you want the wind to help your ventilation system. For a tunnel house, this means the inlet end faces the prevailing summer wind. Wind entering the inlet end adds velocity to the incoming air, reducing the work the fans must do. Some growers report being able to run one fewer fan during peak summer conditions when the inlet is properly oriented into the wind.

For a naturally ventilated house, summer wind should strike the sidewalls at an angle rather than straight on. A 45 degree angle is often ideal because it creates a pressure difference across the house that pulls air through the birds. Wind hitting straight into a sidewall can create dead zones where air stagnates. Wind parallel to the sidewall also moves little air through the house.

In winter, the situation reverses. You want to protect the house from cold wind, especially around the inlets and the brood end. Cold wind hitting the inlet end of a tunnel house can cause drafts on the chicks and make the heating system work harder. It can also cause condensation problems if cold air meets warm humid air inside the house.

Winter wind also affects odor and biosecurity. If your house is downwind of a neighboring poultry operation, you will smell their houses whenever the wind shifts. This is not just unpleasant. It can indicate that you are drawing in air that has passed over another poultry facility, which increases your disease risk. Place your fresh air inlets upwind of any existing poultry houses, manure piles, or compost sites on your own farm and neighboring farms.

Wind breaks can modify the wind pattern around your house, but they need careful design. A solid fence or dense tree line close to the house can create turbulence that interferes with inlet performance. A porous wind break, such as a row of trees that allows 40 to 60 percent of wind through, is better. Place wind breaks at least 100 feet from the house so they do not block airflow to the inlets.

Solar Path and Heat Load

The sun moves across the sky differently in summer and winter, and this affects how much heat strikes each wall of your house. Understanding the solar path at your latitude helps you choose an orientation and design features that reduce heat load.

In the northern hemisphere, the sun rises in the east and sets in the west, but its path is higher in the sky during summer and lower during winter. A house with its long axis running east to west has its largest wall areas facing north and south. The south wall receives direct sun for most of the day in winter when the sun is low, which can help warm the house. In summer, the sun is high overhead, so the south wall receives less direct radiation, especially if you have a roof overhang.

A house with its long axis running north to south has its large walls facing east and west. The east wall gets direct sun in the morning and the west wall gets direct sun in the afternoon. This creates two problems. First, the afternoon sun on the west wall is the hottest part of the day, and it heats the wall just when the outside temperature peaks. Second, the heating is uneven, with one side of the house much warmer than the other at different times of day.

Roof design also affects solar heat gain. A light colored or reflective roof can reduce heat entering the house by reflecting solar radiation. White or galvanized metal roofs reflect more heat than dark colored roofs. Roof insulation is equally important. A well insulated roof can reduce the heat load in summer and heat loss in winter. The insulation value you need depends on your climate, but most commercial broiler houses in temperate regions use R 19 to R 30 insulation in the ceiling.

The sun also affects the brood end of the house. Many growers brood chicks at one end of the house, often near the control room. If this end faces west, the afternoon sun can make the brood area too hot in summer and create wide temperature swings. If it faces east, the morning sun helps warm the house after a cool night. Consider which end of the house will be the brood end and how the sun will affect that area during the first two weeks of each flock.

Topography and Drainage

The land you build on is as important as the direction the house faces. Water is the enemy of a broiler house foundation, litter quality, and bird health. You need ground that drains well and does not collect standing water.

The ideal site is the highest practical point on your property with a gentle slope of 1 to 3 percent. This slope allows surface water to drain away from the house while still providing a level pad for the building. A slope steeper than 3 percent may require excessive grading and can create erosion problems. A slope less than 1 percent may not drain adequately.

Do not build in a low spot. Low areas collect cold air at night, creating frost pockets that can make the house harder to heat in winter. They also collect water during heavy rain, which can flood the foundation, wet the litter, and attract flies and rodents. A house in a low spot will have persistent litter moisture problems that are nearly impossible to fix without major renovation.

Check the water table before you build. If the water table is within a few feet of the surface, you will have problems with foundation seepage and high humidity inside the house. A simple test is to dig a hole 4 to 6 feet deep and see if water collects in it. If it does, you need to either find a different site or install drainage tile around the foundation.

The soil type also matters. Sandy and loamy soils drain well and make good building sites. Clay soils hold water and can become unstable when wet. You should have a percolation test done to measure how fast water moves through the soil. This test is standard for septic system design, and the same principle applies to your building pad.

Grading around the house should direct water away from the foundation on all sides. The pad should be slightly higher than the surrounding ground, and ditches or swales should carry water away from the building. Do not create a situation where water from a nearby field or driveway runs toward the house. This is a common mistake that causes foundation problems years later.

Distance Between Houses and Setbacks

Broiler houses need space between them for several reasons. Airflow, fire safety, equipment access, and biosecurity all require minimum distances. Your local regulations may specify these distances, but even without regulations, you should plan for adequate spacing.

The minimum distance between two broiler houses on the same farm is typically 50 to 100 feet. This distance allows air to move between the houses and prevents one house from blocking the airflow to another. It also provides access for feed trucks, litter removal equipment, and fire trucks. If you plan to expand later, leave enough room between the first houses so you can add more without crowding.

The distance between the inlet end of one house and the outlet end of another is more critical than the distance between sidewalls. If the exhaust fans of one house point toward the inlet of another house, you will pull hot, humid, dusty air from the first house into the second. This is a common problem in older farms where houses were built close together without considering airflow. The minimum separation between the exhaust end of one house and the inlet end of the next should be at least 100 feet, and more is better.

Setbacks from property lines and neighboring homes are also important. Most local ordinances require poultry houses to be set back from property lines and residences. These setbacks are meant to reduce odor, noise, and fly problems for neighbors. Even if your area has no zoning, it is wise to place the house as far from neighbors as practical. A good neighbor relationship is worth more than the extra land you might save by building close to the property line.

Biosecurity distances are a separate consideration. The distance between your farm and the nearest other poultry operation affects your disease risk. Airborne transmission of some diseases, particularly avian influenza, can occur over short distances. While you cannot control where neighbors build, you should place your house as far from other poultry operations as your property allows. Some industry guidelines suggest at least 500 feet between farms, but check with your integrator or local poultry association for specific recommendations.

Access for Equipment and Vehicles

A broiler house is serviced by large vehicles on a regular schedule. Feed trucks deliver feed, often daily. Live haul trucks load birds at the end of each flock. Litter spreaders remove spent litter. Fuel trucks deliver propane or diesel. Service trucks visit for maintenance. All of these vehicles need a solid, accessible route to the house.

The driveway or access road should be at least 12 feet wide to accommodate trucks, with wider sections or turnarounds where needed. The road surface should be all weather, meaning it can handle heavy trucks in wet conditions without becoming impassable. Gravel or crushed stone over a compacted base is the most common choice. Paved roads are better but more expensive.

The road should approach the house so that trucks do not have to back up long distances or make difficult turns. A loop road that goes around the house is ideal but requires more land. A turnaround area at the end of a dead end road is a practical alternative. The area in front of the loading end of the house needs to be large enough for the live haul truck to position for loading birds.

Consider the location of the feed bins. Feed trucks need to access the bins without driving over areas where birds might be released or where litter is stored. The bins are typically placed at one end of the house, often the service end. The access road should bring the feed truck to the bins without crossing the main flow of bird movement during loading.

Fire access is a legal requirement in most areas. Fire trucks need to reach the house from at least two sides, and the access road must be wide enough and strong enough to support fire apparatus. Check with your local fire department about their specific requirements. A fire lane around the house, at least 15 feet wide, is a good practice even if not required.

Water Supply and Quality

Broilers drink a lot of water, and the supply must be reliable and clean. A broiler house with 20,000 birds can use 1,000 to 2,000 gallons of water per day, and more in hot weather. You need a water source that can meet this demand consistently.

The first question is whether you will use a well or a municipal supply. Wells are common in rural areas, but the well must be capable of producing enough water without going dry. A well test should be done before you commit to a site. The test should measure the flow rate and the static water level. A flow rate of at least 10 gallons per minute is often recommended for a commercial broiler house, but this depends on your bird numbers and climate.

Water quality is just as important as quantity. Have the water tested for minerals, bacteria, and pH before you build. High iron or manganese can stain equipment and promote bacterial growth in the water lines. High salt content can cause wet litter and reduce bird performance. Bacterial contamination is a disease risk. If the water quality is poor, you may need a water treatment system, which adds cost and maintenance.

The water line from the source to the house should be buried below the frost line to prevent freezing. The line should be large enough to deliver the peak flow rate, which occurs during hot weather when the birds drink more. A pressure tank and pump system should be sized to deliver water at the pressure needed for the drinker lines and any cooling systems.

Consider backup water supply in case of power failure or pump failure. A storage tank with enough water for 24 hours is a good investment. Some growers install a generator to keep the pump running during outages. The cost of a backup system is small compared to the loss of a flock from dehydration.

Power Supply and Backup

Broiler houses depend on electricity for ventilation, lighting, feeding, and water. A power outage during hot weather can kill a flock in a matter of hours. Your site selection and house design must account for reliable power and backup systems.

The power supply should be three phase if available, because three phase motors are more efficient and reliable than single phase motors. Check with your local power company about the availability of three phase power at your site. If it is not available, the cost of bringing it in can be significant, and you need to factor that into your budget.

The distance from the power source to the house affects the cost of installation and the quality of power. Long runs of wire can cause voltage drop, which makes motors run hot and reduces their lifespan. The power company can advise you on the wire size needed for your distance and load.

A backup generator is essential for a commercial broiler house. The generator should be sized to run the critical loads, which include the ventilation fans, the controller, the water pump, and the lights. The generator should be automatic, meaning it starts within seconds of a power failure without someone having to go to the house. It should also be tested regularly, at least once a month, to ensure it starts and runs properly.

The generator location is part of the site plan. It should be placed away from the house to reduce noise and fire risk, but close enough that the automatic transfer switch can connect to the main electrical panel. The generator should be on a concrete pad and protected from the weather. Fuel storage for the generator should be sufficient for at least 24 hours of continuous operation, and more if you are in an area with frequent storms.

Biosecurity and Disease Prevention

Biosecurity is the set of practices that prevent disease from entering your farm and spreading between houses. Site selection and orientation play a role in biosecurity because they influence how air, water, and people move around the farm.

The most important biosecurity consideration in site selection is the distance from other poultry operations. The closer you are to another farm, the higher your risk of airborne disease transmission. Some diseases, like avian influenza, can be carried on dust particles and in feather dander. If your house is downwind of an infected farm, you are at greater risk.

Your own farm layout also affects biosecurity. The service room or office end of the house should be upwind of the bird area. This keeps odors and any airborne particles from the birds away from the area where people enter and exit. The service room is where you change boots, wash hands, and keep records. It should be the cleanest area of the farm.

The loading area for birds is a biosecurity risk because live haul trucks come from other farms and the processing plant. These trucks can carry disease on their wheels, floors, and crates. The loading area should be located so that trucks do not have to drive past the main entrance or the service room. Ideally, the loading area is at the opposite end of the house from the service room, and the truck access road is separate from the main farm road.

Dead bird disposal is another biosecurity consideration. The disposal site, whether it is a composter, incinerator, or pit, should be located away from the house and downwind of the fresh air inlets. It should also be accessible for the disposal service truck without that truck having to pass close to the house. Your site plan should include a designated route for dead bird removal that does not cross the path of feed delivery or live haul traffic.

Pest Control and Wildlife

Rodents, flies, and wild birds are more than a nuisance. They can carry diseases and contaminate feed and litter. Your site selection and house design can help reduce pest pressure.

Rodents live in burrows and travel along regular routes. A house built on a clean, well drained pad with a gravel border is less attractive to rodents than a house with tall grass and weeds around the foundation. The area around the house should be kept mowed and free of debris. A gravel strip 3 to 5 feet wide around the foundation creates a barrier that rodents are reluctant to cross.

Flies breed in wet litter and manure. Good drainage around the house and proper litter management are the main defenses. The site should not have standing water, which is a breeding site for flies and mosquitoes. If your area has a fly problem, the house should be oriented so that the exhaust air, which may contain fly eggs and larvae, is blown away from neighboring properties and your own service areas.

Wild birds are a serious disease risk because they can carry avian influenza and other pathogens. The house should be designed to exclude wild birds, with netting over inlets and screens on any openings. The site should not have trees or structures that attract wild birds to roost near the house. If there are trees close to the proposed site, consider whether they will attract wild birds and whether you should remove them.

Step by Step Site Selection Process

The process of selecting a site and orientation should be systematic. Follow these steps in order to avoid missing something important.

Step 1: Gather local data. Collect wind roses for all four seasons from the nearest weather station. Record the solar path for your latitude. Note the average temperatures, rainfall, and snowfall for your area. This data is available from your local agricultural extension office or weather service.

Step 2: Map your property. Draw a map of your land showing property lines, existing buildings, roads, water sources, power lines, and any easements. Mark the locations of neighboring homes and poultry operations. Note the topography with elevation contours if possible.

Step 3: Identify potential building sites. Walk the property and look for areas that are high, well drained, and accessible. Mark these potential sites on your map. Consider each site for its exposure to wind, sun, and view from neighbors.

Step 4: Evaluate each potential site. For each site, consider the following factors: drainage, water table, soil type, access to water and power, distance from neighbors and other poultry operations, and the ability to orient the house correctly. Score each site on a scale of 1 to 5 for each factor.

Step 5: Choose the best site. The site with the highest total score is your best choice. If two sites are close in score, consider the intangible factors like the view from your house, the ease of building, and the potential for future expansion.

Step 6: Determine the orientation. Using your wind data, determine the prevailing summer wind direction. For a tunnel house, orient the inlet end toward this direction. For a naturally ventilated house, orient the ridge so the sidewalls catch the summer breeze at an angle. Adjust for solar considerations as described above.

Step 7: Test the soil. Have a percolation test and a water table check done on the chosen site. Also test the soil for bearing capacity if you are building a large house. These tests cost money, but they are much cheaper than fixing a foundation problem later.

Step 8: Check regulations. Contact your local planning department, zoning board, and environmental agency to confirm that your proposed site and house meet all regulations. Get the required permits before you start construction.

Step 9: Finalize the site plan. Draw a detailed site plan showing the house location, orientation, access roads, parking, feed bin locations, dead bird disposal, and any drainage features. Review this plan with your builder, your integrator if you have one, and your extension agent.

Common Mistakes in Orientation and Site Selection

Many growers make the same mistakes when they build their first house or expand their farm. Knowing these mistakes can help you avoid them.

Building in a low spot is one of the most common and most costly mistakes. The land may be cheaper or the view may be better, but a low spot will cause years of problems with moisture, frost, and disease. The few thousand dollars you save on land will be spent many times over on extra heating, wet litter problems, and higher mortality.

Orienting the house without checking wind data is another common error. A grower may orient the house to face the road or to match the neighbor's house, without considering the prevailing wind. The result is a house that is hard to ventilate in summer and hard to heat in winter. This mistake is almost impossible to fix after the house is built.

Placing the inlet end of a tunnel house toward the winter wind is a frequent problem. The grower may have been thinking about summer ventilation and not considered the winter. Cold drafts on the chicks cause poor early performance and higher fuel bills. If you have a choice, it is better to have the winter wind hit the exhaust end of the house.

Building too close to the property line or to a neighbor's house creates problems that can last for decades. Odor and flies from your operation will irritate neighbors, and they may file complaints that lead to legal action. The money you save on land is not worth the risk of a lawsuit or a court order to change your operation.

Forgetting about future expansion is a planning mistake. You may only need one house now, but you may want to add a second or third house in the future. If you build the first house without leaving room for expansion, you may not be able to add houses later without major rework. Plan the whole farm layout before you build the first house.

Ignoring the water supply is a critical mistake. A site may be perfect in every other way, but if the well cannot produce enough water, the house will never perform well. Always test the water supply before you commit to a site.

Decision Thresholds for Site Selection

Some site conditions are deal breakers. If you encounter any of the following, you should seriously consider a different site or a different location on your property.

A water table within 3 feet of the surface is a serious problem. The foundation will be subject to constant moisture, and the house will have high humidity and litter moisture issues. You could install drainage tile, but this adds significant cost and may not solve the problem completely.

A flood risk from a nearby river or stream is an absolute deal breaker. A house that floods once is a total loss. Check flood maps before you buy or build. If the site is in a flood plain, do not build there.

A percolation rate that is too slow for good drainage is a warning sign. If water sits on the surface for hours after a rain, the soil is not suitable for a broiler house without extensive drainage work. A soil test can tell you the percolation rate before you commit.

A distance of less than 500 feet to a neighboring poultry operation is a biosecurity concern. You cannot control what your neighbor does, and you cannot control the wind. If you have a choice, build farther away.

A lack of three phase power within a reasonable distance is not a deal breaker, but it is a significant cost. Get a quote from the power company before you decide. The cost of bringing in three phase power can be substantial, and you need to know this cost before you commit to a site.

Monitoring and Recordkeeping

Good recordkeeping starts before you build and continues through the life of the house. Your records help you make better decisions, troubleshoot problems, and defend your practices if questions arise.

During the planning phase, keep records of your site selection process. Record the wind data you used, the soil test results, the water test results, and the reasons you chose the site and orientation. These records are valuable if you ever need to explain your decisions to a lender, an integrator, or a regulator.

During construction, keep records of the building materials, insulation values, equipment specifications, and any changes from the original plan. These records help you understand the house's performance and plan maintenance. They are also useful if you sell the farm, as the buyer will want to know what is in the walls and under the floor.

After the house is in operation, keep records of ventilation settings, temperature, humidity, litter moisture, and bird performance. These records help you fine tune the ventilation system and identify problems early. If you notice that one end of the house is always warmer or cooler than the other, your records can help you determine whether the problem is related to orientation or to equipment.

Record any changes you make to the ventilation system, such as adding fans, changing inlet sizes, or installing new controllers. Note the date and the reason for the change. This helps you evaluate whether the change achieved its goal.

Keep records of energy use, including electricity and fuel. These records show the efficiency of the house and help you identify problems. A sudden increase in energy use may indicate a ventilation problem, an insulation failure, or an equipment malfunction.

When to Call a Veterinarian or Extension Agent

Site selection and orientation are planning decisions, but they can affect bird health in ways that require professional help. If you notice patterns of disease or poor performance that seem related to the house design, call your veterinarian or extension agent.

If you have a recurring problem with respiratory disease that is worse at one end of the house or in one particular house, the problem may be related to ventilation and airflow. Your veterinarian can help you rule out infectious causes, and your extension agent can help you evaluate the ventilation system. A smoke test can show airflow patterns and identify dead zones where air does not move.

If you have persistent litter moisture problems that you cannot fix by adjusting the ventilation, the problem may be related to the site drainage or the orientation. Your extension agent can help you evaluate the situation and recommend solutions. Some solutions are simple, like improving drainage around the foundation. Others are complex, like modifying the inlet system.

If you suspect that the house is drawing in contaminated air from a neighboring operation, call your veterinarian and your extension agent. They can help you assess the risk and recommend measures to reduce it. This may include changing the ventilation settings, adding air filtration, or in extreme cases, changing the location of the inlets.

If you are planning a major renovation or expansion, call your extension agent before you start. They can review your plans and help you avoid mistakes. They can also connect you with other resources, such as the USDA Natural Resources Conservation Service, which may offer technical assistance for farm improvements.

Frequently Asked Questions

What is the best orientation for a tunnel ventilated broiler house?

The best orientation for a tunnel ventilated house places the inlet end toward the prevailing summer wind. This reduces static pressure and allows the fans to move more air with less energy. In most climates, this means the house runs with its long axis roughly perpendicular to the summer wind direction. Check your local wind data to confirm the prevailing direction before you finalize the orientation.

How far should a broiler house be from a property line?

The required distance from a property line depends on your local zoning and setback regulations. Common requirements range from 50 to 200 feet. Even if your area has no setback requirement, it is wise to place the house as far from property lines as practical to reduce odor and noise complaints from neighbors. Check with your local planning department before you build.

Can I build a broiler house on clay soil?

You can build on clay soil, but you need to address the drainage problems that clay creates. Clay drains slowly and holds water, which can cause foundation problems and high humidity inside the house. You may need to install drainage tile, raise the building pad, or import better soil for the pad. Have a percolation test done before you commit to a clay site.

Should the service room face a particular direction?

The service room should be upwind of the bird area so that odors and airborne particles from the birds do not blow toward the entrance. The service room is where people enter and exit, and it should be the cleanest area of the farm. Orienting the service room upwind also helps keep the control room and equipment area cleaner.

How much space do I need between two broiler houses?

The minimum distance between two broiler houses is typically 50 to 100 feet. This allows for airflow between the houses, equipment access, and fire safety. The distance between the exhaust end of one house and the inlet end of the next should be at least 100 feet to prevent the exhaust air from one house being pulled into the next.

What is a frost pocket and why does it matter?

A frost pocket is a low area where cold air collects at night. Cold air is denser than warm air, so it flows downhill and settles in low spots. A broiler house in a frost pocket will be harder to heat in winter and will have larger temperature swings. This increases fuel costs and can stress the birds. Avoid building in low areas that are prone to frost pockets.

Do I need a backup generator for a broiler house?

Yes, a backup generator is essential for a commercial broiler house. A power outage during hot weather can kill a flock in a matter of hours. The generator should be sized to run the critical loads, including ventilation fans, the controller, and the water pump. It should start automatically and be tested at least once a month.

How do I know the prevailing wind direction for my site?

The best source of wind data is a weather station near your site. The nearest airport or agricultural weather station can provide wind roses, which show the direction and speed of wind for each season. You need at least one year of data, and five years is better, to understand the prevailing patterns. Your local extension agent can help you find and interpret this data.
