If they're stuck, just cut the bottom out of your enclosure... if you intend on selling your babies, you'll pay for the encloure with just one. Or you can just put a square of timber over the hole later. If it looks like they're stuck..I wouldn't risk damaging them. But that is just my opinion.. in the end, it's all up to you honey. Good luck with them all, and I hope they all hatch out nicely for you.
There is a thread on here somewhere about exactly this... you may want to do a search on it. If I can find it, I'll post a link.
