I know you're anxious to see what you've got in the eggs but unless there is some indication that something is wrong (i.e. veins deteriorating and/or no movement when candling, fungal growth, no pipping days after siblings have pipped, etc.) I wouldn't cut. You said yourself that the little one is "lively" in the egg. That would indicate to me that it's healthy and should have no trouble pipping and emerging on its own. If it were me, I would let them all pip on their own. I'm one of those odd balls that consider pipping to be an important milestone that shouldn't be bypassed just because of impatience, though.
