I never cut unless everyone has pipped and out and one doesn't. I have hatched 100's of ball pythons and never cut and consequently have never had an unabsorbed yolk sac either. I have also seen them vary up to 10 days difference in hatching time. My theory is they are ready when they are ready, not when you are.
To each his own, I don't look down on anyone who cuts but I feel nature knows better than me and I go with the flow and prefer not to force the issue. That's just how I roll![]()
