Blind?????

[louisianarednek]

We recently set 7 eggs under a broody hen to just see how it would go I have hatched eggs in the incubator but never under a hen so the days past and the baby's were ready we had 3 healthy babies but the fourth had to be helped out of the egg and we left it with moma while we took the other three to the brooder and left number four under moma overnight this morning number four was a happy little baby bouncing around close to moma but when I put it in the brooder I saw its eyes were cloudy and it didn't move I would put my hand close to its head and it wouldn't move. So is this a phase or is it blind. If so I don't know what to do with a blind chick someone help
