Have you read the article on assisted hatching? It has lots of information about how to know if assistance is needed, and when the chick should be left to keep doing things at their own pace.I think it’s shrink wrapped

Two quotes:
"True shrinkwrapping does not happen as often as people say."
"What happens in shrinkwrapping is that the internal membrane pulls away from the shell and shrinks down over a chick so tightly that it cannot move to turn or get out of the egg."
