i do not know the breed, 2 are white one is brown and 2 are black, the one i'm worried about is black, i'll post pic's tomorrow for comparison
there are some feathers trying to come in but the chick has some bare spots on its wings too, it seems a little slower than the other chicks too, they come right to me and follow me right out to their coop in the evening and all seem to know the routine (they are free-range) they stay around and they are really cool but the little one stays back and always gets lost on the way to the coop and then looks around and peeps until i coax her with food, we thought maybe it was just a runt and not as clever as the others... hmm
thanks for the posts
