I sure hope these do. I think I'm most worried because they are call ducks. What I read says that the babies have such tiny beaks that they have a hard time pipping. I've helped chicks before when necessary so maybe with everybody's help - we can get these hatched!
Once the eggs have rested for 24 hours, candle them and tilt them sideways. You'll see if the air pocket/cell inside moves to the top, or stays in the fat end. If the eggs were very fresh when sent to you there shouldn't be much of a air pocket/cell though, so it should be fine
If the air cell is moving around they will have to be incubated upright until lockdown, or it's going to develop on the side of the egg, making it about impossible for the duckling(s) to hatch.
I don't have a hygrometer....but with chicken eggs I've always incubated dry until lockdown. We have enough natural humidity that it's never been an issue. But as best I recall I kept water in the reservoir for the goose eggs and misted them lightly towards the end.... I'm just gonna give it the best I've got and hope for the best!
