Hello, I have a Buff(7 mo) that seems to not be eating or drinking much. Her crop is practically empty and she's very thin. However, she is not acting any different. I wouldn't have even noticed anything was wrong if I hadn't picked her up and realized how skinny she was. She is still laying eggs but they have what looks like calcified specks on them but that's how they've always looked. I was thinking about worming her. Any wormer suggestions?
