I bought a chick from the store yesterday and it seemed fine at the store, but when I got home all it did was sleep. All the others were sleeping too, so I let it be. Today, it is still sleeping while the others run around it. When I pick it up, I can roll it over and pet it and walk around with it, and it doesn't do anything but blink slowly and go back too sleep. I don't think its more than a few days old and it is a bantam. Can it be sick? What can I do to help it?
