Update!! The second chick to pip, only one to zip, is now out of the shell. A little miracle. It's still moving around and trying to stand it looks like and is loud. Hopefully it will encourage the other chick that has pipped.
I heard the chick in the kitchen so I went in there and saw it was VERY close so I was able to call my son in so he could watch it hatch.

Great news! Awesome that your son was able to watch too!
