Thanks for the references, but I'm sure it's not a prolapsed vent. The vent looks clean and normal. The bulge is down from the vent, not up. It has stool in it. She is pooping fine. Still waiting for an egg since putting her in the box inside yesterday. When I felt up from the vent yesterday, there was no obvious egg. She is eating and drinking well - she just looks at me like, "why am I in this stupid box?" The only sign I had that something was wrong was that her tail was drooping a bit and there was this red pouch on her hind end that had no feather left on it. Any other thoughts???????
