if the membrane is solid white, it is not shrink-wrapped. When the membrane start drying out, it starts turning a tan color. If you had to pip the egg for it, I don't think there is any way that it could have become shrink-wrapped. It just isn't ready to hatch
I agree... If it hasn't even piped the inner membrane it isn't ready.. I would ensure the humidity stays up and its membrane stays moist at this point.
