I have a one year old white leghorn banty with a prolapsed oviduct. She's had it for a long time (I'm a new chicken owner and didn't catch it early on. I did the treatment I read about (prep H on it, then gently pressed back in) but the prolapse reoccurred. She can't keep herself clean and looks pretty uncomfortable, is picking off feathers where she can reach. Any other cures or should I think about putting her down? These are our first chickens, so it's a difficult decision! Thanks for any help.
