4 Safety Tips for Chicken Heat Lamps

Avoid Chicken Coop Heating Tragedies with These Tips


Everyone has seen the 250-watt red heat bulbs. Every feed and hardware store stocks them and many poultry keepers have a chicken heat lamp in their coop. Running an extension cord to the coop and slapping a heat lamp in there is a quick and relatively painless fix for the cold temperatures; however, using a chicken heat lamp introduces combustibles and electrical hazards into the coop, which in turn can cause fires and destroy your flocks (and your home).

Here are four ways to avoid fire hazards in a chicken coop and safely use red heat bulbs.

1. Stay Away From Combustible Fuels

Combustible fuels are everywhere in a coop. The bedding for chickens (when dry) can be a quick igniting and fast burning fuel with an auto-ignition point of only 212ºF. The plywood your coop will also combust when heated beyond 400ºF. Seeing as a heat lamp bulb’s temperature can reach over 480ºF, both of these are a concern. A 24-inch minimum distance is a desirable rule of thumb for bedding, walls and ceilings. Distance your chicken heat lamp as far away as practical from anything that may melt or catch fire such as chicken nest boxes and chicken feeders.

Electrical hazards are easily avoided but commonly overlooked. Electrical fires are caused by resistance heat or arcing, and I’ll explain what that means to us.

Extension cords are how many of us get power out to our coop since few of us have the luxury of hard-wired power in our barns. If you use an extension cord you should:

2. Check Your Extension Cord For Damage

Check the cord for cuts, abrasions or pinch marks. Don’t use a damaged cord for anything, period. If buying new, spring for the thicker gauge cable, usually labeled as 12/3 wire. Your typical cheap 16/3 gauge cord tends to be more prone to damage.

3. Seal Extension Cord Connections

If you must connect multiple cables, be sure to shelter or seal connections. I suggest using 3M brand electrical tape liberally if you need to seal junctures exposed to the weather. Leaving your connections exposed to the weather introduces water to the connection, which will short the circuit and corrode the connectors. If the connection becomes corroded, resistance will cause the connection to create heat and may cause a fire.

4. Use The Right Fixture

Fixtures are not created equal. I’ve unfortunately seen people use lamps known as “painter’s lamps” to install their 250-watt red heat bulb. Painter’s lamps look like a chicken heat lamp, but they’re not. The difference is the fixture (where the bulb screws in). Painter’s lamps are rated to a maximum capacity of 100 watts and are built with a plastic housing. Brooder lamps use a porcelain fixture so that the fixture does not melt under the heat of a 250-watt bulb. Using a 250-watt bulb in a 100W rated fixture is a recipe for disaster that may cause the fixture to melt. Fire will shortly ensue.


This porcelain fixture on this 250W rated lamp won’t melt from the heat your bulb produces.

Brooder lamps are an easy and popular way to heat your coop, but be sure to understand the inherent risks. Be sure your lamp is rated for 250 watts or higher. When used properly and maintained correctly, a brooder lamp will keep your chickens warm and safe through the cold winter nights.

  • Don’t use anything to heat the coop. Chickens are well insulated with their down feathers. They squat on their roost pole so their feathers keep their feet warm. They roost close together for the same purpose. Mine do fine through blizzards, and although they prefer not to walk in the snow, they will to get food. I usally spread out hay over the snow before putting out scratch. Scratch feed before bedtime is als reputed to keep the chickens warm due to digestive heat. We are in New York, but I have heard of coops in Minnesota and Alaske which do not have a need for heaters. You might also look into deep litter bedding.
