My 2 yr old Amerucana died this afternoon unexpectedly and I think it is all my fault! I had her in a cage on the patio under a ceiling fan for the past 4 days for bully behavior to a new chicken. She had plenty of water/food - she was laying eggs. I was even taking her out and putting her in a run that I have so she would get exercise until I could reintroduce her into the coop. Granted, she was not enjoying the "incarceration", but I thought she had creature comforts. This afternoon she was making weird noises and looking up at the ceiling and walking around in a weird way. I decided when it cooled down I would end her incarceration as it must be making her crazy because that is the only way to describe her behavior. An hour later I went out and she was laying down with her head sticking out of the cage - mouth open and drooling. She was alive. I picked her up - tried to see if she could stand - she could not, but she could hold her head up. I thought she might be dehydrated so I got an eye dropper and brought her into the a/c house and gave her water a few drops at a time and fanned her. I noticed that she had rubbed her feathers off her neck and wondered if she might have broken her neck, but she was able to hold her head up and did not appear to be in pain. She failed fast - within 20 minutes she was gone. I was devastated! Did I do this to her? Could she have stressed herself out - thus the strange behavior - which might have caused a stroke or something? She had been acting so aggressive the last month......almost like a rooster if you know what I mean. I still feel so guilty. If anyone has an idea - I would so appreciate reading it.
