Help with duck eggs

[hholzschu]

We set several different breeds of duck eggs. We kept the temp and humidity right according to the paperwork sent with the eggs. We candled and marked the eggs before lock down and thought they looked good. On day 26 we had one khaki cambel duck hatch and nothing else. Today makes day 29 and nothing from the rest. We've hatched before but just chickens never ducks. I don't know how long we wait before we consider the rest duds! Or if we should just give them more time. Thanks

What temp and humidity have you had them on? Have you seen any rock or cheep?

I'd leave them anouther day before candling them, and looking for movement.

Good luck
