Hello, I have a six week old Ameraucana and she is acting sick. Last night, when I put them to bed, all the chicks looked and acted fine. This morning my Ameraucana "Cleo" is lethargic, not eating or drinking, and warm to the touch. None of the other chicks seem to be affected. I'm a first time chicken mom so this is all new to me. Any advice on what to do?
