i started out with 5 texas blue scale quail. over the past two days two have died and one looks all fluffed up. we have been having colder weather with fall coming on. i live in alabama so its not extreme. i keep the quail in a 8 x 8 coop on the ground with coturnix quail. the only symptom are being fluffed up. when i examine them after they die it looks like they just shut their eye and went to sleep. their craws are empty. any advise would be appreciated. they are about 5 months old and are eating game bird starter.
