should hatch around 24hr after pipping, if it will not hatch its self its will not survive anyway. when it gets up moving around and fluff out them membrane should just fall off if you can take your finger and lightly flake it off, i would let nature take its course as much as possible
To raise the humidity i added a small fish tank bubblier or a big one with adjust valve on it, in a cup of water or in the bottom if it holds water in the bottom
Also helps with keeping humidity when you open and close the lid
