I'd give him a good hour before you help. He doesn't have any yolk or anything attached, correct? If he does than leave him be for sure. Otherwise, he should be able to kick it off eventually on his own and you don't want to be opening the incubator too much.
The baby that has pipped on the wrong end is still ok, I can see the egg moving around and the hole is big enough to breath so we are ok right now!
