Not yet! I have had them hatch up to 2 (almost 3) days after they have pipped. Do not open the incubator, and keep the humidity up! If the egg dries out the duckling can get stuck, and you may have to help it out after all, but not yet.
Ok it looks moist still this morning but it still hasn't moved at all I've lost one already to drowning it piped low I think this one I piped a bigger hole for its beak 12 hrs ago but it's still hanging out its going on day 3 if it's not over day 3 already. I have a wet sponge in there as well as a damp paper towel on the shell
