Today two out of my 9 quail have become very droopy, like no energy. One does seem to also have a sore leg, it has been eating, drinking, pooping and even played an egg. The others beak seams to be a little off, the top half looks to be about 1 millimetre shorter. She is currently in a triangle wire hutch with 4 others for a number of weeks with no signs of trouble. Has anyone experienced something like this? Any suggestions?
