OK so give it some time, hatching takes a very long time. If he still isn't out bytomorrow night or the next day, I would try cracking open the shell. I had to do that with a few of my chicks, by the time that I even cracked it open, the shell membrane was already dried onto the skin and they had crooked toes. I wouldn't worry too much about that. But if you see some movement in a few of the eggs, then I would think that just giving them some time and letting them try to crack open up on their own would be good. But if not by tomorrow night or the next day I would maybe try cracking one open.
