I have a chick that has been badly pecked on the head by another hen. It seems slower than normal and keeps closing its eyes. Also it seems concussed. I thought it had been got by a predator as the mother hen lost it in the morning. In the evening it turned up again with the rest of her chicks. But its got a small wound just above its eye and one on the back of its head. It looks like its been pecked by another hen and it was knocked out cold. I think its been in a daze hiding in the tall grass all day. Will it recover? Its walking about.. and keeping up with the others.. but its wobbly and slow.
