Hi I got 15 chicks two weeks ago. All growing like weeds. Then yesterday this guy isn't hardly moving. No other signs at all that there is a problem. No poo on butt, nothing!! Just can't seem to support himself. I isolated him and he does eat and drink a bit, mostly sleeps. It has been 24 hrs with no change. Any idea's?? Should I be concerned about the rest of the chicks? Theresa PS they are still in the house and we have no other chickens around.
