We have this chicken that is a little over a year old and we went out to check on them and my son's fav hen has this hanging out of her. What is it? What should we do?? Update: I gave her a bath this morning to clean it up a bit. I felt it and it is just full of air. It will colapse when you touch it. Does this help at all?? See how its got that curl on the end of it...is that any help??
