One of my favorite chickens dropped dead a few days ago. Literally, dropped dead. There were no wounds, blood, nothing. I found her on the floor of my coop, and it seemed like a lot of the hay had been moved out from under her, like a nest type thing. She was about 7 months old. Her behavior had been completly normal for her and it really just came as a devastating shock. Her name was Henrietta and she was a golden campine. If you have any idea what might have caused this please help. Thanks.
