If the hole is getting bigger don't worry, I usually intervene if it goes more than 24 hours with no change. Just SLOWLY and CAREFULLY peel some of the shell of by the beak. If you see any blood stop immediately.
If the membrane is stuck to the chick it means it got dried out. Use warm water to wet it down with your fingertips.
If membrane seams fine you can either put it back in after the beak is clear, or try to peel it more. If there is no blood at all it means the chick is ready.
I would try clearing the beak and seeing if that's enough to get the little one zipping the egg.
