He may need to absorb the yoke still. If his head is out and he can breath I would wait a while. I had to help one last hatch and he was tired and stayed in the shell after I had peeled it away around his head. When he finally go out of the shell he had the cord still attached to the shell. It was very thin and clear so I ended up cutting it. If it were dark or red I wouldn't do that because he could bleed from that. It was just so hard for him to move around with the shell attached and it looked like it might tear so I did it. It also takes some longer to get out of the shell. They say some times up to 10 hrs or so. I have never had one take that long though. It seems that some membranes and shells are much harder than others also. I was told that I might have to help the Americana eggs I got in the last hatch because the membranes were very hard. I did just break the membrane of one that pipped but didn't break the membrane. I was afraid it would not be able to breath. I am not going to do nothing if I think I can help. I have not had any die from my helping a little. If the membrane has veins showing it isn't ready yet and will bleed.Sooo....I chipped a lil shell and membrane from the top and the baby chick is now moving his head around like the first one did and is also moving his feet....however he still cant come out of his lower part of the shell....seems like hes stuckk....i am just going to let it be and wait it out....what do you guys think???
