Tonight as I was shutting the birds up, I noticed one of my Dark Brahmas had bloody feathers around her rump area. Not very much, but enough to draw my attention. Upon closer inspection, there seemed to be tissue protruding from her vent area. I assumed prolapse and brought her inside and drew her a warm bath. After a thorough cleaning, we then began to examine the area more in-depth. Whatever it is appears to be attached to the outer skin of the vent and doesn't look to be actually protruding from the vent itself, if you look closely. It only takes up the top left edge of the vent. We tried to push it lightly up in towards the vent, but it would not slide in. She's isolated now in the same condition (however cleaner). We didn't want to force anything up there that wasn't supposed to be there. So now I'm doubting prolapse and thinking some sort of growth maybe? Thoughts? Oh and her vent was moving and puckering as normal as well. Her behavior was normal through the day today also. Any input is welcome. Thanks!
