My ducks have been laying but not to regular. One day i will find one and the next 2 and the next nothing and one day i found 4. I do have one that has started to lay in a nest and has 5 in there. How many do they lay before they sit and how many can they sit on at at time. I did collect 10 in a week and put them in the bator, they are on day nine and 8 of the ten are developing. When the hen hatches hers do i need to keep them seperated from the rest or can they all be be together. I have 5 hens and 2 drakes.
I've always taken the ducklings away when they hatch so the other adults won't hurt or kill them. Ducks as a rule aren't usually the good mothers that hens are.
