Heating a Chicken Coop: When & Why, How and When Not

You may be worried about heating your chicken coop when winter arrives. Mostly, chickens are cold-hardy.

They puff up their feathers to trap air and stay warm. Chickens can easily tolerate 45–50°F. But when it’s freezing cold, it’s time to think.

When chickens are exposed to prolonged freezing temperatures, they need some extra care.

In our farm, we provide heat to our chickens only when the temperature goes below 35°F. 

But for baby chicks, the thing is different. Chicks need a little more heat, so we provide them with a different brooding setup during cold weather.

Mostly, we do brooding at night, and during the daytime, they get natural brooding from the mother hen when foraging outside.

In this definitive guide, we will explain why and when you might heat the chicken coop, how to do it safely, and when not to heat.

Why Consider Heating Your Chicken Coop

Every chicken farmer wants to keep their chickens healthy and warm during freezing winters. So they consider heating their chicken coops.

If you do not provide additional heat inside the chicken coop in low environmental temperatures, it can lead to cold stress in the flock.

Always watch for signs and symptoms like huddling, shivering, or birds tucking a foot to their warm breast. 

These signs and symptoms mean your flock is losing more heat than it can generate. 

Additionally, some chicken breeds are less cold-hardy: large dual-purpose breeds (like Orpingtons or Wyandottes) usually handle winter well.

On the other side, chicken breeds like Anconas, Minorcas, Sebright, and a few other bantams or crestless breeds do not handle cold well.

In extreme cases, prolonged exposure causes cold stress in chickens, which can be fatal.

Chicken breeds with large combs are more susceptible to frostbite during extreme cold weather. Injured, sick, or elderly birds mostly struggle to stay warm in severe cold. 

That’s why giving them additional gentle heat keeps them warm and cozy during freezing temperatures.

In all these cases, supplemental heat can prevent frostbite and hypothermia. For example, a tiny 60–80W heated mat mounted at roost level gives hens a warm gathering spot.

We recommend the popular Farm Innovators 60W Heated Chicken Mat.

When to Consider Heating the Chicken Coop

• Save

You don’t need to grab the heat lamp every time it gets cold. Most of the time, your chickens handle chilly weather better than you think. What matters is how the outside cold mixes with how well your coop holds heat.

As a general rule, many chicken keepers use 35 degrees Fahrenheit as a mark. When temps drop below that, you might think about adding some warmth. 

A good thermometer inside the coop, close to the roost, helps you keep track. This way, you check the actual temperature, not just guess.

Still, don’t go by numbers alone. Always check the weather forecast. If the temperature suddenly drops, like a 20-degree fall overnight or several days of single digits, that’s a warning sign. Cold winds and snow can push even hardy hens to their limits, so watch out for those, too.

Now look at the birds you have. If you’re raising chicks fresh out of the brooder, they’re not ready for the cold. The same goes for pullets that haven’t grown full feathers yet. They need help staying warm, usually with a safe brooder plate or a gentle heat source.

Small flocks can also struggle. If you have just a couple of hens in a big coop, they can’t make enough body heat. Some breeds, like Silkies, Frizzles, or Polish, don’t hold heat well because of their feather type. 

Even birds with big combs, like Leghorns, are more likely to get frostbite. In these cases, a low-wattage roost heater can help a lot.

If one of your hens is recovering from an illness or injury, warmth is a must. Heat is not optional in this situation; it is essential.

Finally, during long stretches of freezing weather, it’s smart to have a backup plan. Even your strongest birds will feel the stress if the cold never lets up.

Still, in most parts of the U.S. and western countries, you won’t need to heat the chicken coop daily during winter. 

A dry, draft-free, and well-insulated space is your best tool. Save heating for when your flock truly needs it, not just because the thermometer drops.

How to Heat A Chicken Coop (Safe Methods & Equipment)

If you decide to heat, you need to do it safely and efficiently. Focus on radiant heat sources that warm your birds directly, not just the air around them. 

Here are the top options that I’ve tried on my backyard farm.

Radiant Panel Heaters:

These flat electric panels warm your chickens using radiant heat, kind of like sunlight but without the bright light. You can mount them on the wall or ceiling inside the coop. 

They create soft, steady warmth and don’t need extra space around bedding, which keeps things safe and simple.

One great example is the Farm Innovators 2-in-1 Radiant Chicken Coop Heater. It runs at 200 watts and also works as a 50W brooder plate. 

Since it’s ETL-certified and has a built-in thermostat, you get reliable heat while saving energy. In fact, it uses way less electricity than a standard 150W lamp.

Cozy Products offers a similar 200W flat-panel heater that’s designed for small chicken or pet coops. You can mount it near the top or along the side wall. 

It runs quietly and adds just enough warmth to keep the coop from getting too cold throughout the year.

Heated Mats (Chicken Pads):

A heat mat works kind of like a foot warmer, giving your chickens a cozy place to rest on chilly days. 

The Farm Innovators 60W Heated Chicken Mat is a great example. It turns on automatically when the temperature drops near freezing and can be placed on the floor or mounted low on a wall. 

Your chickens can stand or lie on it to warm up. Since it’s low wattage and safely sealed in plastic, it works well even near bedding without causing any risk.

Infrared Heat Lamps:

Even though traditional heat lamps can cause fires, a carefully used infrared bulb might work as a focused heat source. 

If you choose this option, pick a ceramic infrared bulb and pair it with a strong UL-rated clamp lamp that has a built-in guard. 

For example, Fluker’s 250W Infrared Coop Lamp gives off steady warmth without messing up your hens’ sleep. 

Always mount the lamp securely, never by the cord, and keep it at least 12 inches away from any straw or bedding. 

A metal shade, like the Woods 150W Clamp Lamp, helps keep the bulb contained. Still, only use heat lamps if no other heating option works well for your setup.

Electric Space Heaters (Caution): 

Last update on 2025-08-02 / Affiliate links / Images from Amazon Product Advertising API

Electric heaters, such as ceramic or fan types, do warm the air, but honestly, they’re not the safest option in a chicken coop. 

Fire risk is real. If you’re set on using one, your best shot is an oil-filled or ceramic heater that has both tip-over and overheat shutoff features. 

Set it up on a concrete block or metal stand—something sturdy and well above the bedding.

This isn’t a method most backyard keepers swear by. We’re just putting it out there for DIY folks. If you try it, keep the wattage low—under 500 watts. 

And seriously, only run it when you’re around. Chicken coops need air to move through them. You can’t close them up like a regular room without causing other problems.

Safe Thermostats and Timers:

No matter which heater you use, you should always pair it with a thermostat or timer. A smart outlet like the ThermoCube TC-3 can be very helpful. 

It turns the heater on only when temperatures drop near freezing—say, on at 35°F and off at 45°F. 

This way, the heater won’t run all night when it’s not needed. It saves power and keeps things more consistent for your flock.

DIY and Natural Heat Tricks That Work

You don’t always need fancy gear to keep your chickens warm. These low-cost ideas can help during cold snaps.

Try the deep-litter method. Pile up 6 to 8 inches of straw or pine shavings on the floor and let the droppings build up. Over time, the mix breaks down and gives off a bit of heat. This composting layer can keep the coop around 10 to 20 degrees warmer than the outside. It won’t heat things instantly, but it builds a steady, free heat source that works all winter.

Insulate with what you have. Stack straw bales along the coop walls or add foam boards to trap heat. Even an old tarp or thick blanket hung on the inside (where chickens can’t peck it) makes a difference. Believe it or not, snow packed around the outside acts like an insulating igloo. So don’t clear it all away.

Feed extra before bed. Give your birds cracked corn or scratch grains in the evening. As they digest it, they build body heat. Those late treats can help them stay cozy through the night.

Use hot water bottles in a pinch. Heat glass bottles and tuck them into a bucket where the flock can huddle nearby. It’s not high tech, but it helps. Reheat and repeat each night during extreme cold.

Let sunlight do the job. If your coop has clear windows facing the sun, leave them uncovered during the day. The sun’s rays can warm up the space. Even black buckets or roofs will absorb sunlight and give off a little warmth later on.

Safety Tips When Heating Inside A Chicken Coop

Heating a coop carries fire risk, so focus on safety first. So, follow proper installation and vigilance:

Secure and Isolate: 

Mount heaters (panels, bulbs, etc.) well above the bedding. Keep any heat source at least 6–12 inches from straw, wood shavings, or droppings. 

For example, if you use a heat lamp, never hang it directly into the litter; clamp it to a wall or ceiling and make sure it’s tight. 

So, it is always important not to hang a lamp by its cord and use a guarded lamp with a protective metal cage to avoid breakage.

Use Certified Equipment: 

Choose heaters listed for livestock or “outdoor use”. Many radiant panels, like CozyProducts or Farm Innovators models, come with ETL/UL approvals and built-in thermostats or thermal cut-offs, making them much safer than a bare bulb. 

Do not use homemade wire lamps. Always plug heaters into properly grounded outlets. Use short heavy-duty cords (no long extensions through the coop) and consider an outlet with a circuit breaker.

Thermostat Control:

As mentioned, plug your heater into a thermostat (e.g., ThermoCube) set to engage only in freezing temps. This prevents an unattended heater from running all night once it’s warm enough, lowering both fire risk and power use.

Ventilation & Moisture: 

Counterintuitively, too much warmth in a poorly ventilated coop causes moisture buildup and frost on combs. Maintain at least minimal ventilation (small vents or partially open windows) to let moisture escape. 

Dry air and a dry coop floor are essential; wet litter plus heat creates ammonia fumes and frostbite risk. Keep litter changed regularly or use the deep litter method carefully.

Fire Prevention Practices: 

Remove all clutter and flammable materials from around heaters. Always remember that straw and wood shavings “catch on fire so easily” under a lamp. 

Regularly inspect wires and plugs for damage. Do not use seedling heat mats or other indoor pet heaters as coop heat – they aren’t rated for livestock and often fail. Always have a functioning smoke detector or extinguisher near your coop when using electricity.

Monitor Constantly: 

First, check your heater daily. Feel around it for hot spots. Look for any frayed cords (hens love to peck wires). 

If you smell burning, shut it off immediately. Unattended heaters cause many fatal coop fires. The University of New Hampshire bluntly cautions that “the risk of a heat source causing a fire is too high” in a coop, so if you heat, lean on caution. 

For extra peace of mind, only heat during freezing periods and unplug or shut off when the barn is warm enough.

You minimise risks by following these rules: set a safe lower temp trigger, secure the unit, and ventilate. 

Keep all wiring off the ground and away from chickens or waterers. A little planning makes coop heating quite safe.

When Not to Heat The Chicken Coop

Often, the best action is no heater at all. Poultry experts generally advise against supplemental heat except in the cases above. 

Why? First, adult chickens are built for cold: they originated in chilly mountains and have fluffy down under their feathers. 

Healthy birds naturally maintain 106°F internally, even when the air is far colder. With enough flock-body heat, insulation, and ventilation, a coop can stay survivable without added heat.

Normal Winters: 

In most northern, western, or temperate climates, winter nights dip well below a comfortable range (45–65°F), but the dry cold is usually tolerable.

A coop that keeps out drafts and moisture is often enough. If a coop is “properly constructed” (dry, draft-free, ventilated), it should suffice to protect your flock on most cold days. 

Many chicken keepers find that chickens prefer it colder than humans – a warm barn can lead to overheating or disease. In fact, 

Few chicken experts advise making the coop draft-free and letting chickens be cold-hardy unless they are unusually vulnerable.

Ventilation Over Heat: 

A far bigger threat than cold is moisture. Poorly ventilated coops trap humidity from breath and droppings; in below-freezing temps, this causes frost on combs. 

It’s better to add a vent or use a desiccant than to crank up the heat. The UMN guide reminds us that “high moisture in a coop, combined with cold temperatures, can lead to frostbite. 

For example, on a dry winter night, you might see your coop hit 30°F, but the birds are fine. If that night had 90% humidity, the chickens could suffer frostbite without any heat lamp. So always fix drafts and dampness first.

Deep Litter and More Birds: Before buying a heater, try natural warming tricks. Remember, snow makes an excellent insulator – piling it around coop walls can raise temperatures. 

Their blog even boasts that 21 hens in a deep-littered coop ran 10–20°F warmer than outside from body and compost heat. 

In short, adding a few hens can often eliminate the need for a heat source if your coop is large. It sounds funny, but “more chickens” is a tried-and-true way to heat a coop without electricity.

No Need for Continuous Light: 

Some newbies heat with bright bulbs, thinking of “warmth,” but chickens do not need light or warmth all night. 

USDA poultry extension warns against using light bulbs (which produce heat) purely to raise light levels in winter; only do so carefully and sparingly. Chickens are fine roosting in darkness, and turning on lights can confuse their sleep cycle.

In summary, you should not heat if your coop is adequate and your birds are normal. In most circumstances, we advise against adding supplemental heat”. 

Instead, spend effort on insulation and ventilation. Ensure roosts are above the floor (so birds huddle with their warm feet up). Brush petroleum jelly on exposed combs on the coldest nights to prevent frostbite.

Keep bedding dry and maybe add a toss of scratch grains – all of these help chickens stay comfortable without any lamp.

Overall, think twice before heating: if your birds are feathered, active, and not showing cold-stress signs, they’re probably fine without a lamp. Use heat as a precautionary tool for extremes or weaker birds – never as a regular need. This keeps your flock safe (fewer fire hazards) and healthy (preventing respiratory issues from overheated or damp air).

Always remember, the safest coop heat is often no direct heat, just good coop design. Between a well-sealed coop, deep bedding, and healthy flock behavior, your chickens can usually brave winter quite happily.

Conclusion

Heating your chicken coop isn’t always a must, but sometimes it really helps your flock. The trick is knowing when to use it—and when not to.

If you’ve raised chickens through a few cold snaps, you’ve probably seen how tough they are. Healthy adult birds can handle temps well below 45 degrees, as long as they’ve got a dry, draft-free space to roost.

But cold isn’t the same for every flock. If the thermometer dips below 35 and stays there, and you’ve got young chicks, older hens, Silkies, or birds recovering from illness, they may need some help staying warm. Tiny flocks also struggle to keep body heat in.

At that point, using a low-watt radiant heater or a heated mat might make sense. These don’t just heat the air—they gently warm your birds, which is much safer. 

Just make sure any heater is certified, has safety features, and is set up correctly. A thermostat or timer helps prevent accidents and keeps the heat from running all night.

Now here’s the part people forget: most chickens don’t need heat in winter. Overheating can actually cause more harm than cold. A sealed-up coop without airflow leads to moisture, and moisture means frostbite and breathing issues.

So, focus first on good design. Use deep litter to hold warmth, add ventilation up high, and seal out drafts at roost level. When your coop is built right, your chickens stay warm the natural way—and that’s always the safest bet.
