Around 8pm this evening I went outside to check my coop for the night and one of my chickens was laying in the run. She was listless with her eyes closed and head on the ground. She was still breathing. I was worried an animal had possibly gotten to her because there were feathers scattered around her. I picked her up and she was able to open her eyes and lift her head. She is now resting in my air conditioned house and has a small fan running close to her. Since she was brought inside, I have been able to give her a few sips of water. She is laying on her side but will occasionally move her legs and neck and can briefly stand when I pick her up. Is this a case of heat exhaustion? My chicken is 3 years old and has had no other heath concerns before. Does anyone know what might causing this? I’ve already checked her for broken bones and external parasites. Any ideas are appreciated!!!
