Well, my rooster has suddenly become very lethargic. He stares off into space like he is in a trance. He is not eating or drinking. He had pure white diarrhea yesterday, but today it is bright green. I called the vet and left a message for him to call me back so I could make an appointment. He has never called back. Any suggestions. What should i do? These are my first chickens and I am clueless.
