How to Tell If Your Chickens Are Too Cold
Winter weather brings new challenges for backyard chicken keepers. While chickens are surprisingly cold-hardy, there are limits to what they can tolerate. So how do you know if your chickens are too cold—and what can you do about it?
This guide will help you identify the signs of cold stress in your flock, what temperatures are dangerous, and how to keep chickens warm and healthy through the coldest months of the year.
How to Tell If Your Chickens Are Too Cold
Chickens that are too cold will show signs like huddling, shivering, puffed-up feathers, slow movement, or frostbite on combs and toes.
While chickens are equipped with feathers and a high metabolism to handle chilly weather, extended exposure to freezing temperatures—especially without adequate shelter—can lead to cold stress, illness, or even death.
Top Signs Your Chickens Are Too Cold
Here are the most common symptoms of cold stress in chickens:
1. Huddling in a Tight Group
When chickens are cold, they instinctively huddle together to share body heat. While this is normal at night, excessive huddling during the day—especially near coop corners—can indicate they’re struggling to stay warm.
2. Fluffed or Ruffled Feathers
Chickens puff up their feathers to trap warm air next to their bodies. Constant fluffing, even when not resting, suggests they’re cold and trying to insulate themselves.
3. Tucked Heads and Standing Still
Cold birds often appear lethargic, standing still with their heads tucked into their chests and feathers puffed. This posture helps conserve heat but signals distress if prolonged.
4. Shivering or Trembling
Yes, chickens can shiver. It’s rare, but if you notice trembling, it’s time to take action. Shivering means they’re using muscle energy to stay warm—something they can’t do for long.
5. Cold Feet and Combs
Frostbite commonly affects combs, wattles, and toes. If you touch your chicken’s feet and they’re icy cold or you see dark, pale, or blackened comb tips, intervene immediately.
6. Decrease in Egg Production
Extreme cold causes hens to conserve energy by reducing or stopping egg laying. A sudden drop in eggs during cold snaps could be weather-related.
What Temperatures Are Too Cold for Chickens?
Most healthy chickens can tolerate temperatures down to 20°F (-6°C), and some cold-hardy breeds can go even lower. However, wind, moisture, and drafts can make milder temperatures dangerous if the coop isn’t properly insulated or ventilated.
Breed Matters
- Cold-hardy breeds: Orpingtons, Australorps, Rhode Island Reds, Wyandottes
- Less cold-tolerant: Leghorns, Silkies, Bantams
How to Keep Chickens Warm in Winter
Keeping chickens warm doesn’t mean heating the coop—it means keeping it dry, draft-free, and well-ventilated.
1. Insulate Without Sealing
Use straw bales, foam board, or thick walls to insulate the coop. But don’t seal it airtight—ventilation is vital to prevent moisture buildup and ammonia accumulation.
2. Deep Litter Method
Let bedding build up during the fall and winter months. The deep litter method creates natural warmth from composting pine shavings and manure. Just stir it weekly and remove soiled spots.
3. Block Drafts at Roost Level
Chickens lose the most heat at night. Make sure roosts are away from windows, doors, and ventilation vents. Use curtains, feed bags, or boards to block direct airflow.
4. Provide Wide Roosting Bars
Use 2×4 wooden boards with the 4-inch side facing up. This allows chickens to fully cover their toes while sleeping, reducing frostbite risk.
5. Offer Warm Water and Protein-Rich Feed
Chickens need extra calories to generate body heat. Offer cracked corn in the evening to boost nighttime energy and ensure they always have access to unfrozen water.
6. No Heaters Unless Absolutely Necessary
Heat lamps pose a serious fire risk. Only use heaters in extreme cases and with proper safety precautions. Most chickens will do fine without supplemental heat.
Cold Stress vs. Illness: Know the Difference
Prolonged cold exposure can weaken a chicken’s immune system, making them vulnerable to respiratory infections and illness. Watch for these symptoms:
- Wheezing or rattling breath
- Runny nose or watery eyes
- Lethargy, not moving or eating
- Swollen comb or face
Natural remedies can help support your flock’s health during cold months. The Doctor’s Book of Survival Home Remedies offers dozens of DIY herbal treatments for respiratory issues, digestion, immunity, and skin health—perfect for off-grid or chemical-free care.

How to Warm Up a Cold Chicken
If you suspect a chicken is dangerously cold, take these immediate steps:
- Move the bird indoors to a warm, dry space (garage, mudroom, laundry room)
- Wrap in a towel or blanket to retain heat
- Offer warm (not hot) water with electrolytes or sugar
- Don’t use direct heat like hairdryers or heating pads directly on skin
- Monitor closely and reintroduce to the coop only after full recovery
Prevention is easier than emergency care. Know the signs and check on your flock regularly during extreme cold snaps.
Best Cold-Hardy Breeds for Winter
Planning to expand your flock? Consider breeds known for winter resilience:
- Buff Orpington
- Plymouth Rock
- Australorp
- Dominique
- Wyandotte
These breeds have dense feathers, smaller combs, and calm temperaments that help them thrive in colder climates.
Conclusion
Knowing how to tell if your chickens are too cold can save you from heartache and health issues. Look for puffed feathers, huddling, frostbite signs, or changes in behavior, and act quickly to improve warmth and shelter.
