I know this is an old link, but thank you. We are hundreds of miles away from home and got a call from our friends that our Runner Duck has a prolapse. They took her to their house to care for her. I'm hoping for the best, but who knows. Any new suggestions are appreciated. They are reading, and watching videos to make sure they do the right thing. They said she had about 6 in. out and the other ducks were picking on her. They found the egg she laid and it was bloody. I know they are doing all they can for her. She was given to us, so we can only estimate her age at about 3 yr. old. None of the ducks have been laying very good this spring.
