isolating a bird

[agoodegg]

recently I isolated a 4 month old hen with a prolapse, but got discouraged and returned her to the flock too early. I just felt bad about keeping her in, as she seemed miserable. Now I realize that she is not healing properly and seems to be in pain, so I'm making one last ditch effort before I give her away to a friend who will no doubt slaughter and eat her. I am fond of this bird, though, and want her to live!
She has been in my tub in a cardboard box with a perch for 48 hours so far. It is almost entirely dark in there. I give her a food and water break every 6- 8 hours and change her soiled litter. She has laid 2 eggs over the 2 days. How long will it take for her to stop laying? I just finished a 3 day course of 1ml Pepto Bismal 2x/day, as advised by a vet to coat her insides and maybe ease her troubles with pooping and laying. Her butt does look a bit cleaner.
In addition to her prolapse, she definitely has a soiled backside that sometimes is caked with poop and/or blood. She was successfully treated for coccidiosis, but still has the dirty butt. I bathe her regularly, but have not cut or plucked any feathers. Please offer any advice you can!! She's very sweet.

Have you tried Preperation H? It shrinks swelling and you can use a little inside her.

I did not use the prep H as I read some conflicting info about whether or not it works. I felt that getting her to stop laying for a time might really help her to heal. The prolapse is rarely exposed anymore, but I see it pop out when she poops. Regardless, I do see that she is trickling blood down her backside sometimes, and it's hard to tell whether it's coming internally from her vent or maybe farther down from clumped up feathers.
