My young hen has a full squishy crop. Yesterday while i was holding her upside down to check her vent she vomited on me..at first I thought it was poo? After reading up here I really think her problem is a full crop. She wont eat, sits alone fluffed up and does this weird movement with her head. My husband said her crop was full...now I need to know what can I do to help her? Can someone please help me? Do I make her vomit, and if so how?
