I have never had one get stuck. I initially used a different lingerie bag that was way tighter mesh and sort of shiny and that was so difficult to see through that I just tossed it when it was over. But I get the concern bc I was at first, too. I do try to pull them 1-2 times a day once we are past the first couple that always seem to be much earlier than the others. Seems they can find trouble anywhere, though. I had a new hatchling mangle a leg in the brooder overnight (I brood outside) and get stuck just outside the heat plate. She was cold but alive when I found her but the foot was almost severed and it was an immediate cull.

So, things can happen at any time, really.
At least you have a couple you know for sure and you can possibly tell them apart from various things later! I am sure it is very frustrating for now, though!
