Hello! We recently got some quail, around July. One of our coturnix quail was walking around slowly and we noticed a huge sack like ball protruding from her vent. I've done some research and everything I've found only relates to chickens. I don't think it was a vent prolapse because everything I've seen with a prolapse, the pictures show a little tiny bit poking out from the vent. The ball that was protruding from our quail was almost half the size of the quail itself and it gave a rank smell; which led me to believe it could've been vent gleet but all the pictures I've seen with vent gleet shows runny diarrhea like symptoms. Not a huge ball sack like thing coming from the vent. The big sack protruding from the quail was a bit squishy and was not an egg. I'm really at a lost at what it could've been or what happened. I would really like to get to the bottom of this issue especially if I could prevent it from happening again. Sadly, I had to put the quail down, but I would love to know if anyone else has heard or seen this happen before.
