I had this happen early this summer with a 4 week old chick. She had poo all over her and it was really raw. For 3 days I continually washed the area in warm water and chlorhexidine, would apply preH and push it back in. It kept coming back out. One morning I didn't want to deal with it anymore...I was thinking of having her euthanized. I went to work without checking on her, but when I got home that evening and checked on her it was all back in place and she has been fince since! What did help, which I had read on here was to push it in and hold it in for a least a minute, to allow the nerves to settle down and the contractions to stop. In this case persitsence paid off.
Good luck with your little one!
