Well, Rosie's sutures were starting to come out of their own accord anyway, so we went ahead and removed them this evening. Nothing popped back out! She's looking really good, she's eating and it appears she has reintegrated back into the flock. Tomorrow we'll put her out with the others for good, and I'll be keeping a close eye on her to see how she does when she starts laying again. I think we may have pulled through this! After reading so many cases of prolapse that ended in tragedy, I've been really worried for Rosie, but I think she's going to be okay.
