My little barred rock just started to be a little lethargic yesterday afternoon. She's drinking but I haven't seen her eat. She is just sitting on a little roost I have in the brooder with the 5 other (very active) chicks. She's not acting like the others this morning at all. What should I do. No vet around here that I know about. She peeps when I pick her up but doesn't try to get away. Eyes bright, Poop is runny. HELP. These are my first chicks.
