We have had two quails die within the last 4 weeks. The first one no one witnessed, we came home and it was warm and probably died 20-30 minutes earlier. No injuries, just on the floor dead. After checking if it was egg bound, green liquid poop was coming out of her. Just a few minutes ago i was woken by my mother who had just been out at the quails and when she left she heard one cry. When she went back to it (It was in the same cage as the other one that had died) she picked it up and it's chest was puffed up, and apparently it had trouble breathing and was vomiting out water everywhere. I have been searching online and can't find anything. Did it have impacted crop, or some disease? I feel this is what killed the other one. There is only one left in that cage now.
