Does this post from @sylviethecochin help?

Like chickens, ducks can store sperm for long periods (according to the internet, up to sixteen days), so you'll want to separate your ducks from undersirable drakes at least two and a half weeks before you start collecting eggs for brooding.

If your weather is anything like it is here (Northern PA) then they'll start breeding in late March/early April.

Ducks can hold sperm for up to 30 days
