The inner membrane after you get shell exposed. You will also be watching for bleeding. If there is a lot of blood, you will need to stop for a while. Make sure the duckling can breath--nothing blocks the airway. If possible you can also use a dropper to give it a drop of water
Go slowly but I do not see too much blood. Work on clearing the head and try getting a feeling on if the yolk has absorbed. It is ok to get the head out and if the yolk is absorbed, remove the rest of the shell. Be careful because some times there is a bit of umbilical cord attached to a piece of yolk. That cannot be pulled on or the intestines can come out.
There will be blood--that is a part of it. I have to take calming breaths sometimes but push through. It is tough but worth it when you have a nice healthy new flock member!
likely still absorbing some yolk. Did it drink some water?
