Should You Consider Heat Lamps for Hens in Winter?

April 5, 2026

Quick Answer

Consider using heat lamps for hens in winter if you live in an area with extremely cold temperatures, have a large flock, or are raising young or broody hens, but ensure proper ventilation and monitor the temperature closely.

Heat Lamp Benefits for Hens

Heat lamps are an effective way to maintain a comfortable temperature for your hens in cold winter months. A temperature range of 40°F to 60°F (4°C to 15°C) is ideal for egg-laying hens. To determine the correct heat lamp size, consider the coop’s cubic footage and the number of hens. A general rule of thumb is to provide 2-4 square feet of space per hen. For example, a 4x8 foot coop will require a 300-400 watt heat lamp. Ensure that the heat lamp is at least 18 inches off the ground to prevent hens from roosting too close and overheating.

Setting Up Heat Lamps Safely

When setting up heat lamps, it is essential to ensure proper ventilation to prevent ammonia buildup and maintain air quality. A ventilation rate of 20-30 air changes per hour is recommended. You can achieve this by installing windows, vents, or fans. Additionally, keep the heat lamp at least 3 feet away from any combustible materials, such as bedding or nesting boxes. Monitor the temperature and adjust the heat lamp accordingly to prevent overheating, which can lead to stress, reduced egg production, and health issues.
