My hen Quinny (she is about 2 years old ) has been sick for 2 days. (One other hen was acting lethargic) We thought she had sour crop at first and we vomited her over the toilet and she seemed to feel better, she had very bad diarrhea, this morning I made her eggs with some regular food and grit mixed in but she refused to eat and her crop was empty. She’s very lethargic I don’t know what to do.
