You also need to start your own thread here to prevent confusing birds:My 8 week old chicken is having this same issue. Large squishy crop. I don’t feel an obstruction and her breath does not smell but her crop will not go down. This is day 3 and she has not eat since yesterday. She is still pooping. However last night and this morning she was acting a little less like herself. I think I may have to try and get her to throw up if her crop is still large when I get home. Any advice?
