First time hatching ducks! Need help!

[FrizzleFreak]

So today I got my new little foam Hovabator...and naturally, I got some eggs to go in it!

They are Saxony ducks, and I'm really looking forward to having ducklings! However, I need to know what about duck incubation is different from chicken incubation. I know that I'm looking at 28 days instead of 21, and that I need higher humidity, but other than that I'm pretty clueless. Will somebody please help me out?

You can put wet sponges in the bottom of the incubator to increase the humidity.
I dip the eggs in warm water when I turn them.
Othere then that treat them like chicken eggs.
