Can you still see then moving their bills and "yawning"? If they make that yawn motion, they are still absorbing yolk. If you see them start struggling, and looking like they are trying to zip and can't, then you might want to help.
IF you help, just remove the shell over the round end first, where it would naturally zip. Moisten the membrane (coconut oil or Vaseline) and check for blood vessels before peeling any membrane back. Let the duckling kick out on its own when its ready. It could be right when you help, or it could take a while longer.
