So I have the same issue... our chicken is 6 months old and she just started laying, though I am not positive I ever did receive an egg from her as we have 5 other hens.
My wife noticed that she had an egg bound problem, and I promptly conducted a google search and followed that advice, which was to soak her in a warm water bath. After soaking her, I found not one, but TWO eggs that came out... one was perfect, the other had little cracks in it (to me it sounds like a calcium problem).
I lathered her up with honey and pushed the prolapse in, which it stayed for about a minute... and then she pushed it out again. I put more honey on her, and then pushed it in, and then placed her in a box for the next couple of days, isolating her from the other chickens.
We are now on day 3 (I have also added prep-H to her regiment in the morning, honey at night), and I have a nice black mess... she ic preening herself, eating like a champ and drinking like a champ. I am about to put her in a open air cage and allow her to have some sunlight (didn't do it up to this point as I didn't want her producing more eggs).
It seems to have gotten a bit better, but she keeps crapping on the prolapse, which I am sure is not helping the infection. I still soak her nightly and as soon as I am done soaking her, she just poops on the cleanness of what I have done. I am about to put some prep-H on the wound... as I think the medicine will help more than the honey.
However, I am curious if this is a lost cause. I have attached a couple pictures of this... I think she should remained isolated, but I am also noticing she pecks at the prolapse from time to time... should I just put her back in the general population?
Any advice is appreciated!
