Hello all, I have an 11 week old Buff Cochin that seems not quite right. She seems to prefer laying around, roosting, moves about slowly, and is very shy. She is not sneezing, does not have any eye or nostril discharge and is eating and drinking just not as aggressively as the rest of my group. She does not have lice or mites or anything else I can see. She is on chick starter, grass, weeds, and bread as a treat. Should I watch for anything or am I being a freak. This is my first time having chickens after taking a 15 year break so any advice would be appreciated.
