I noticed the other day my blk australorp has this poofy bugle under her vent area, not directly under but like a couple of inches down. At first I thought she had an egg stuck but when I touched it, it wasn't hard at all. In fact, it just feels like a big air bubble. I have no idea how long she's had it & it doesn't appear to be getting any bigger. She doesn't walk funny. Still lays, eats & poops like normal, so I'm stumped. Its hard to explain so I'll try to post a pic asap- since I poked around on her last time, she hasn't come near me since, so I may have a time trying to catch her again. But has anyone ever heard of anything like this?
