I don't have any pictures yet, but one of my chickens has a "pouch" looking spot below her booty that's puffy and seems to be full of fluid, id had a chicken laying just a sac with egg whites and no yolk or shell so I thought maybe she had perinitis or whatever its called, so I separated her last night and she laid a perfectly normal egg this morning, and it doesn't seem to be getting worse l, and she runs around just fine, I've read so many things that "could" be the problem going off of just "swollen abdomen"
