Crossing the Road
Ducklings are very slow hatchers and rushing them can result in a premature baby with unabsorbed yolk. Or causing a severe bleed by hitting a blood vessel. Nothing should be done until 48 hours after the external pip. Then, if progress stops, an assist may be required.If he pipped only 11 hours ago, I would keep an eye on him, they can make a lot of progress very fast once they've absorbed the yolk. Since you've peeled some of the membrane I would dampen a paper towel and put it in with him and keep reweting it once it dries. Once you hit 24 hours then I would chip away the egg shell until you can find his beak and then let him go for a little while, 30 minutes or so... As long as he's able to move around he should be able to unzip.
If you're going to chip the egg shell only do it at the spot he pipped and then go left to right. That's how they unzip.
Wet paper towels are commonly used to wrap eggs in, this is bad information as the wet wrap can actually chill the duckling. Rather, applying coconut oil to the membrane will keep it most. Right now this duckling is only just begining to hatch and should be being left alone
