Ok I need help telling the difference between sour crop, doughy crop, and an impacted crop. I believe one of my chickens has one of these. Her crop is large and it is hard. She isn't lethargic and no stink is coming from her. She does have Bumble Foot so we're curing that right now, but I want to rid her of these crop issues (or what I think is crop issues). I don't think she has lost any weight and one morning I felt her crop and it was basically flat, but this morning there was a bump and it was hard. So I'm just wanting to make sure she is okay. She is laying eggs and being a normal chicken so far. Thanks so much!!
