I have a 5 1/2 year old Red Star hen named Gertie. She was fine one night and the next morning she was laying on the floor of the coop. She seems to be blind. One leg is curled up and neither leg works. She can't walk or even sit up by herself. She lays on her side, occasionally flops wildly, and shivers sometimes, even though I'm keeping her warm. The only thing I can get down her is some water-soaked bread squirted down her throat. She has diarrhea and her stomach gurgles. I have her quarantined, and none of the other chickens are affected. I have no idea what could be wrong with her or what I should do for her. I hate to have her put down (she's a pet), but I don't want her to suffer. Any ideas?
