Chicken heat stress
Quick answer
Backyard chickens need **shade, airflow, and multiple water points** in UK heatwaves. Panting with wings spread is heat stress — act immediately. Overcrowded coops and metal runs without shade are common causes of summer losses.
Key takeaways
- Chickens pant with open mouths, hold wings away from body, eat less, and drink more. Severe heat stress causes collapse. Provide shade and water immediately.
- Ensure ventilation, shade over run, frozen water bottles in run, multiple drinkers, and avoid overcrowding. Dark coop roofs absorb less heat than metal sheeting without shade.
- Yes. Heat stress kills backyard flocks every summer. Sudden deaths in hot weather warrant vet contact and immediate cooling for surviving birds.
