My little hen has been sick with respritory infection for a month. She is better still has a way to go but better. She is still sleeping in my house cause we have been having cold nights and she has been so weak she couldn't sit on the roost. she is eating better. my question is this morning when she got up her crop was full and tight. I know she hadn't eaten anything because she was in here. I massaged it some and it was kinda like working playdough. what does that mean?
