It wasn't a crop issue, it was literally her whole body was inflated. I did find that little article about the rooster online but really nothing else so I tried the incision thing. I cut on her side/under the wing to help keep dirt and stuff out and not cut anything important.We made the cut and the air came out and we covered it with neosporin. We did that twice and she is fine now.it was very weird, couldn't find anything about it on backyard chickens and I knew she wasn't egg bound.
Amazing! I will keep an eye out for this in the future.
