This morning I found one of my quail dead. I know she was live at least 2 hours ago- as that's when my son does his morning chores. I go and recheck his chores late morning as a few usually need redoing. I found her still warm 15 minutes ago, but most definitely dead and stiff. The other quail with her seem good, active and up to their usual activities. I have 1 male with 7 females now. Should I do a necropsy? If so what should I look for? Impacted crop?
