How to Winterize a Chicken Coop
When temperatures drop, you need to consider your flock's comfort and health during the winter months. Chickens are remarkably hardy animals, but a little preparation can make a big difference in keeping them warm, productive, and safe.
Have you started checking your coop for drafts yet? At Kalmbach Feeds, we've gathered expert guidance to help you protect your birds from cold stress, maintain egg production, and ensure your coop stays dry and well-ventilated all winter long.

Why Winterizing a Chicken Coop Matters
A well-prepared coop keeps your flock healthy and productive despite lower temperatures and shorter days. Winterizing focuses on managing moisture, preventing drafts, and maintaining proper nutrition.
Cold weather presents several challenges for your chickens, including frostbite risk on combs and wattles from high humidity, reduced egg production due to shorter daylight hours, increased energy needs to maintain body temperature, and moisture buildup from poor ventilation, leading to ammonia odors and respiratory stress.
The University of Minnesota Extension notes that most breeds tolerate temperatures well below freezing if they have dry bedding and protection from drafts. The Ohio State University Extension also emphasizes the importance of ventilation and nutrition over artificial heat for most backyard flocks.
Do Chickens Need Heat in the Winter?
In most regions, chickens don't need supplemental heat to survive cold weather. Their feathers provide excellent insulation, and they adapt naturally to seasonal changes. A gradual drop in temperature allows them to grow a thicker layer of down feathers for added protection.
The real key is keeping them dry and out of drafts. Wet feathers lose their insulation value, and damp bedding can increase ammonia levels that irritate respiratory systems. If your hens stay dry, well-fed, and protected from wind, they'll stay warm on their own through most winter weather.
Is It Safe to Heat My Chicken Coop?
Adding heat may seem helpful, but it can introduce serious safety risks. Space heaters and heat lamps can cause fires if knocked over or if dust accumulates on heating elements. Sudden temperature fluctuations can also stress birds or make them dependent on artificial warmth they won't have during power outages.
If you must use heat in extreme conditions, do so with caution and follow the manufacturer's safety guidelines carefully. Choose equipment designed for agricultural or outdoor use, secure cords away from pecking, and never place heating elements near flammable materials.
Safe Heating Options for Extreme Cold
Heated Waterers
Keeping water unfrozen is critical for chicken health during winter. Use heated bases or thermostatically controlled waterers to prevent ice buildup without raising overall coop temperature. Always keep cords outside the pecking range and plug them into GFCI outlets for safety.
Flat-Panel or Radiant Heaters
Mounted radiant panels provide gentle warmth without open flames or exposed bulbs. These can help maintain above-freezing conditions during extreme cold snaps, but they should be placed safely out of reach of curious chickens.
Deep-Litter Method
The deep-litter method offers natural "heating" by using layers of clean, dry bedding like pine shavings that gradually decompose. Decomposition generates mild heat while insulating the floor. Turn the bedding regularly to maintain airflow and freshness.
How to Winterize a Chicken Coop in 7 Steps
Follow these practical steps to prepare your coop for winter weather and keep your flock comfortable no matter how cold it gets outside.
Step 1: Inspect the Structure
Check walls, doors, and windows for cracks or gaps that allow cold air inside. Seal unwanted drafts with caulk or weather-stripping, but avoid making the coop completely airtight. Ventilation remains essential for controlling humidity levels.
Step 2: Maintain Proper Ventilation
Add upper vents or small openings under the eaves to let moist air escape naturally. Airflow should move humidity upward and out of the coop, not directly across roosts where birds sleep at night.
Step 3: Keep Bedding Dry
Replace damp litter often and stir regularly if you use the deep-litter method. Moisture buildup increases frostbite risk and creates unpleasant odors. Consider a raised floor design to improve drainage if you have persistent moisture issues.
Step 4: Protect the Water Supply
Frozen water is one of the most significant winter hazards for chickens. Use heated bases or switch to rubber tubs that can be emptied easily if ice forms. Check waterers at least twice daily to ensure your flock has constant access to fresh, clean water.
Step 5: Strengthen Winter Nutrition
Cold weather significantly increases calorie needs as chickens burn more energy staying warm. A higher-protein, energy-dense diet supports body heat production and consistent laying through the winter months.
Try Henhouse Reserve®, Henhouse Reserve Love Bug™, or Henhouse Reserve® with Crumbles. All three provide complete, balanced nutrition with wholesome grains, real vegetables, and LifeGuard® and YolkProud® technologies to support immune health and egg quality.
Supplement with healthy treats like Henhouse Reserve Love Bug™ Mealworm Treats or scratch grains for enrichment and extra calories, but keep treats under 10% of the total diet.
Step 6: Adjust Lighting Gradually
Short winter days naturally reduce laying frequency. To maintain egg production, add a low-wattage bulb on a timer to extend daylight to about 14-16 hours per day. Follow safety protocols carefully and never hang bulbs near bedding or where hens can reach cords.
Step 7: Check Flock Health Frequently
Observe combs, wattles, and feet regularly for frostbite or signs of illness. Cold or poor ventilation may stress birds that appear puffed up, lethargic, or not eating. Regular coop cleaning, daily observation, and balanced feed go a long way toward keeping them healthy through winter.
