To cool chickens down, provide plenty of shade, fresh water, and use fans or misters to lower the temperature in their coop during hot weather.
Chickens struggle with heat more than cold. Their normal body temperature runs between 105-107°F, making them vulnerable when temperatures exceed 85°F. Without proper cooling methods, heat stress can lead to reduced egg production, illness, or even death. Here’s how to protect your flock.
Recognizing Heat Stress in Chickens
Watch for these warning signs when temperatures rise:
- Panting with beaks open
- Wings held away from body
- Pale combs and wattles
- Lethargy or reduced activity
- Decreased appetite
- Diarrhea or watery droppings
Heavy breeds like Orpingtons and older birds show stress first. Monitor them closely during heatwaves. For more on chicken behavior, see our guide on why chickens follow their owners.
Water: The First Line of Defense
Optimal Water Systems
Chickens drink up to twice their normal amount in hot weather. Use these water strategies:
| Water Type | Advantage | Tip |
|---|---|---|
| Large buckets (5+ gallons) | Stays cooler longer | Bury slightly in soil to prevent tipping |
| Automatic waterers | Constant supply | Check pipes don’t get hot |
| Ceramic bowls | Cool to the touch | Add marbles to prevent splashing |
Keeping Water Cool
- Place waterers in shaded areas
- Add ice blocks in morning
- Use multiple stations around coop and run
- Clean with 10% bleach solution weekly
According to Chicken Coach, chickens refuse hot water and may dehydrate rather than drink it.
Coop Cooling Strategies
Ventilation Essentials
Proper airflow prevents deadly heat buildup:
- Install roof vents (minimum 15cm gap)
- Replace solid doors with wire mesh
- Add small fans for circulation
- Remove perspex windows
Shade Solutions
- Plant trees near the run
- Install shade cloth (70% UV block)
- Use reflective roofing material
- Create covered dust bath areas

Emergency Cooling Techniques
Quick Interventions
When temperatures spike above 100°F:
- Mist coop roof with water (not birds directly)
- Offer frozen treats (watermelon, peas in ice)
- Provide electrolyte supplements (except during heatwaves)
- Lower perches closer to ground
Nighttime Cooling
Chickens need relief at night too:
- Check coop temperature after sunset
- Ensure adequate roosting space
- Consider temporary relocation to cooler area
- Use battery-operated fans if no electricity
The Purina Animal Nutrition team recommends reducing bedding to 2 inches during heatwaves to prevent trapped heat.
Breed-Specific Considerations
Some chickens need extra care:
- Heavy breeds: Orpingtons, Cochins – more prone to overheating
- Feathered feet: Brahmas, Silkies – keep bedding dry
- Dark-colored birds: Absorb more heat – provide extra shade
- Bantams: Need smaller, accessible water sources
Long-Term Heat Adaptation
Help your flock adjust to seasonal changes:
- Acclimate birds gradually to temperature changes
- Maintain healthy weight (overweight birds struggle more)
- Provide high-quality feed with proper nutrients
- Ensure access to shade at all times
Remember that prevention is easier than treating heat stress. Implementing these strategies before temperatures soar will keep your chickens comfortable and productive all summer long.
