I had a horrific prolapse (my first) in one of my very favorite hens. It was graphic and bloody and horrible. We got the ax out twice to end her suffering and I couldn't bring myself to do it. I stuck with her and I'm going to tell you exactly how we fixed her. (Update:she's still alive and kicking ***!) Step One. We soaked her for a half an hour several times a day in a warm bucket of water. After 30 minutes or so i gently washed the poop and blood and hanging tissue off as much as she would tolerate. Then i towel dried her and squirted a TON of Preparation H on her prolapse and tried to push in as much as shed let me. I did this a couple times a day, for two days. By this time she wasn't actively bleeding anymore so I got Vetericyn in a squirt bottle and would squirt her behind with it multiple times a day. By day 4, nothing was hanging out. All this time I kept her in an old dog kennel in my garage with towels in a pretty dark environment. I was scared shed try to pay again and push her stuff back out. After day 8 she looked completely normal and re-intigrated her into the flock. This was over a month ago. She's laying eggs again and is back to get friendly happy self. I did have a friend say my hens are overweight, and that being too chubby can exacerbate a prolapse so I've cut down on their food.
