Three weeks ago, my chicken got sick. She suddenly became very lethargic and she wasn't eating or drinking much and she had greenish diarreah. I began giving her yogurt and probiotics. I checked to make sure she wasn't egg-bound. I've given her several warm baths. When none of this helped, I gave her a few doses of monistat. Sometimes she appears to be somewhat better. She's now eating and drinking but she is still very lethargic. Sometimes she just lays down in the middle of the yard. I found her laying on her side a few days ago - I thought she was dead. Her symptoms are: Lethargic, droopy comb, diarreah, easily toppled over when one of the other girls bumps into her and when she is standing, she seems to be hunched over all the time. Any ideas as to what this could be? Thank you.
