I've had a hen with a prolapse, had to out it back it couple of times a day with prepH, not the nicest of jobs but it worked. Might be an idea to separate her so the others don't peck it, also if she is laying I have heard it is good to keep her in the dark on corn instead of layers pellets to discourage laying. Mine had it in June and is still fine. Good luck, hope she is ok.
