Night before last my DD accidently locked one of our chickens in the shed instead of the coop. Yesterday after I let her out and so far today she wont leave the coop. She is eating drinking running around in the coop she will even come to the door but she wont go outside. I am thinking it scared her so that she is afraid she will be locked out of the coop again. Do you all think this is it or the begining of being sick?
