It isn't shrink-wrapped as if it were; that membrane would be stuck onto the chick. Since it got its beak out, that's the best part as now it's breathing fresh air and can get the rest of itself out. I'd just leave it be for what could be several hours.She's been chirping and moving around, and I put vegetable oil on the membrane to hopefully prevent shrink wrapping, but how do I tell if it shrink wraps?
