2 weeks ago I went to Meyer Hatchery and purchased a mix of chicks from their bins. Only one of them had pasty butt. After cleaning the pasty butt I noticed she had a prolapsed vent, although at that time I didnt know what a prolapsed vent was. I just knew her butt was hanging out, and I didn't know why. I have kept a close eye on her for a week and a half now. She is eating, drinking, pooping and gaining weight. The other chicks are not pecking at her. Today for the first time I have tried repeatedly to push it back in with a q-tip and vaseline. It will not stay in. Should I just keep trying? Or is it a lost cause?
