We have been out of the house for about 3 hours. It has been well over 100 degrees today. It's finally cooled off to 97. This is our first full summer with chickens. When we got home, our Americauna was panting in the shade of the hen house. She was lying limp. When I picked her up, she was completely limp. I put her in a cat carrier and brought her indoors and put some electrolytes in her water dish. What's going on? Please advise!
