Now that Ren is not here I finally found this info!!! argggg
Why to ALLOW duckling to hatch on its own:
Many people want to help their duckling hatch. It is best to allow them to do the hatching themselves. This process of pecking around in a circle twists the umbilical cord thus no more blood is in the veins of the lining of the shell and the duckling does not bleed when these veinsare broken during the hatching process. The only time you want to help them is when they make a hole and then cannot progress because they are stuck in that spot. If an actual hole is made, and you can see the duckling, but no progress is made for 12 hours, check to determine if the lining has dried to the down of the duckling making it impossible for it to move. This condition can be easily remedied by wrapping the egg with one thickness of cloth or paper towel that has been dampened with warm water and return to the incubator for an hour or so. If the duckling gets stuck after it started to break a circle (two inches or more), it can usually be helped without a problem. But if they are progressing on their own, let them be.
