Can you see his beak? If he hasn't made progress by mid to late afternoon, you can enlarge his pip a bit, and take a look around to see what you see. Before you touch him, do a thread search on assisted hatching. Some folks say that assisting with hatch goes against the "survival of the fittest" and breeding for a strong flock rationale. So, it depends on what your paradigm is. IMO, by choosing to artificially hatch, we're setting up a hatch that may not have the best of conditions. So, I will assist when it's evident that not to do so will result in a dead chick.
