I'm new to this, and I recently acquired 4 quail, but one of the quail didn't look good from the day I got her ((long story--someone else picked them up, or I wouldn't have even brought that one home.) I hoped for the best, and after talking with a few fellow quail owners, I was advised to see if she "improved" with better living conditions at my place. She seemed to be doing OK, and I talked myself into believing that she was "improving." Unfortunately, tonight she looked bad when I went in to feed the quail, and when I checked back an hour later, she was stone cold dead and rigor mortis had already set in. What is my best practice for the other quail at this point? I'm very hopeful that she wasn't sick with anything contagious, but I want to be better safe than sorry. I've removed the dead quail's body, of course, but will a thorough cage clean be sufficient? Also, what can I be watching for with the other birds in case it was contagious? P.S. a few details: when I say she "looked bad" from the first day, the quail had puffy tissue around her eyes, and slightly inflamed nasal area above her beak. She also had a very hooked beak, but that didn't seem to keep her from eating, and her weight was good. But she always looked lethargic compared to the others.
