Yes, or they will bleed the main thing is getting the shell opened more, pick away that white membrane that is attached to the shell. there is another membrane around the chick and that is probably what is int he way and also what will have blood vessels to avoid just open the shell and the memb. that is attached to the shell and see what the chick does give it a couple of hours. You can also wrap the egg with a damp paper towel not covering the opening but to help keep it humid and not dry out.
