If you absolutely cannot wait the normal incubation time, instead of cutting the whole top off and removing it, leaving the egg so open and the babies and egg fluid exposed to the elements, you can cut a much smaller flap. Not actually removing any of the egg shell, but just cut a flap, like two sides of a narrow triangle but don't cut the 3rd side. So you can lift up the small flap, make sure the baby is ok, then close it back down so they are more protected. They'd easily be able to push the flap open when they are actually ready to hatch, but wouldn't be so exposed in the mean time with the whole top of their egg gone. Good luck with the babies and congrats on the Lucy!
