You have to take a prolapse very seriously. If you can't go to a vet, you're going to have to help her yourself ASAP. I have dealt with this before and it was very helpful to read up online and watch some videos on YouTube of people trying to help. The tissue that is protruding has to be put back inside and it's very delicate. It can't be allowed to dry out. First I would allow her to bathe in a lukewarm bathtub in the house. Stage an area for her to stay inside where you can keep a close eye on her. I used a dog crate and draped it with sheets so poop and water didn't splash on my walls. I used KYjelly or honey to very gently finger the protrusion back inside until I could feel it was in place. I used a giant bandaid bandage that had an opening on the edges, so poop could escape, and placed it over the vent to hold the prolapse in place. I had to change the bandaid multiple times so that it didn't get too gross - you don't want to pull her feathers off, so I would just cut it and be careful not to hurt her. You only need to do this if the prolapse keeps popping back out. In my case I put the prolapse back probably 40 times before I came up with the bandaid option - we were both traumatized at that point. Once it started staying in my girl stayed in the house a few more days until it was healed and no longer a problem. Once she laid her next egg in the spring though it occurred again, and sadly we put her down. But many can recover from this! It's just going to take a little work on your part and keeping her inside, dry and clean, where you can help her when needed, for several days. No matter what, don't leave it and let her suffer!
