Is it too late to mark the top of the eggs?

[FatalFramer]

The eggs are 42 days in and I didn't want to mark them at first to see if it would effect their hatch rate. But after hearing that when some of the baby's hatch they can turn the other eggs while their running around I want to mark them now but not sure if its too late or not to do that. She laid 11 eggs and their all doing great.

I highly doubt that hatchlings would be able to turn eggs over. Especially if they are buried 3/4ths down like they should be.

You don't need to mark them.
