So I cut the one remaining egg from the clutch, a week ago yesterday, on day 54. It's now day....62? and the baby is still not coming out and appears that it may still be inside the sack. Should I be worried? There also seems to be quite a substantial amount of yolk left. I know that I'm right on my days because I documented the day I found the eggs, which I'm almost certain wasn't even the same day as mama had laid them.

Sorry if this is a dumb question, never had eggs/babies before!
