Two of my chicks have been breathing weirdly. none of my other chicks do it. when they breathe, their face inflates and deflates. they’re not wheezing, but they are sneezing every now and again. they both have liquid-y poop sometimes and other times it’s solid. they’re still eating and drinking like normal. Also, the one in the picture has a crooked, dry, red comb. Is that normal?
