Inner membrane stuck to chick

[Jennivera]

yesterday around 3, I got my first pip! 3 hourse later, 3 more had pipped. All 3 were hatched by 630, but the one that had first pipped, is still in the egg. I can hear and see it, but it looks like the inner membrane is sticking to the chick. It doesn't look dried out, but the fact that there isn't any progress and its sticking to the chick has me a little concerned. Roughly 20 hours. Now, I'm ok with assisted hatching since I've done it previously and been successful, but I havent had an inner membrane stick to the chick before.

I guess I'm just asking if the inner membrane sticking to the chick will give it problems hatching, like not able to turn properly to zip and if, or when I should intervene
