The one definitely looks to be wrapped in it's umbilical. You may have to try to remove that snake and untangle if it does not start absorbing some of that yolk.
I think you may have been a little too aggressive on the cutting. You really don't need to totally cut a big piece off like that. Just a slit is the best way to go. Good luck.
Agreed - I cut a V shape in my eggs, just enough to allow the animal some air and to peek in and see what I've got. I then pretty much lay it back down over the animal.
