Hello! We have two chickens - BB & Belle. They are a little over a year. I'm worried about Belle and not sure what to do. For three+ weeks now her crop is HUGE in the evenings, she no longer has feathers on it, it's bright red, and she has diarrhea/gas. In the morning, I check their coop and she doesn't seem to go poop while sleeping, but goes first thing in the AM and it's huge! I took her to the vet, he said that she might have sand in her crop (found out sand is a no-no and took it out that very day) & he gave me some antibiotics to give to her. She seemed better on the antibiotics, but she's back to the way she was before. She is still active, still laying, and her crop is completely empty in the mornings. So could this still be sour crop? I've purchased a crop bra that I thought about putting on her, but wanted to check with others before I did. Any suggestions would be greatly appreciated. I just want to help her feel better. Thanks!
