Hi Chrismahon,
Has no one advised you to try anusol? I have used it a few times and it always works for me,I might add that my girls did not sound as bad as yours,they had prolapsed but I always use the anusol on first sight,I do not know what any one else would suggest but this does actually shrink things back,I personally would at least try it before I decided to let her go.
(p.s.,if you go an buy it,don't tell them you wish to use it for chickens!~I purchased some Calendula gel to use on my Sal and was chatting in the chemist and said it was for one of my hens,she said,you are not supposed to tell me that?!!)
Hope this helps?
