I find it hard to wait and let them be... however, when the baby is in the shell, its blood vessels are lined out along the inside of the shell, much like a placenta, so that it can exchange air and moisture with the outside. When it starts to breathe, it uses the air cell and pips a hole for more air. Then it absorbs back its blood supply into its belly and any of the yolk that is left and seals that up, THEN it is ready to enter the world. It can take it a while, even a day, to finish that process. If we help before it has absorbed its "placenta" back into its belly, we will kill it.
One thing I have done that seems to help a weak duckling is to (after its been pipped for a long time - like 8 hours or more- and not making progress) use little hemostats to tear the membrane another 1/4" and to be sure it doesn't dry out too much (the membrane gets really tough and rubbery and it can't escape) by misting it. I figure the duckling still needs to work its way out and exercise the legs and lungs, etc. A duckling that doesn't work enough on the way out may have an open, wet navel and curled up feet. This baby is in danger of not straightening out and of infection of the navel. Then you end up putting tape on the feet and hoping it is strong enough to make it. This is rare on ducklings that I don't help to hatch.
It's difficult to determine when and how much to help. Err on the side of caution, your results will be better and your chicks stronger in the long run. Messing with the incubator to help one weak chick risks fluctuations that harm the others too. I've saved a couple of slow ducklings when the others are done by tearing the membrane that little bit and chipping away a wee bit of shell, dampening them and putting them back for a couple of hours, then doing a wee bit more.
I understand the desire to help, I get very attached to my babies, even while they are still eggs. It helps me to wait, knowing more about the process they go through as they hatch. I find it fascinating!
