Drake fertility / eclipse plumage

[Senna95]

Does anyone know if drakes in eclipse plumage are still fertile?

I just got some ducks that I've been waiting for for a long time, and was hoping to still hatch some eggs from them this year. They're all in their eclipse plumage, and I know it's late in the season. I generally stop setting eggs by the end of May, or early June at the latest.

Another question: How long after separating the ducks from the flock should I wait before I can be sure that the eggs are "pure"? I know that for chickens it can be up to 2 weeks, but I haven't found much information on ducks.

My drake certainly were very fertile over the last few months. I have only had to take two eggs out of the bator in the last few months ( in Australia here- so now in winter. ) My boys nearly have their full colour back- a few more weeks and they will be back to looking their stunning best. My 3 lots of eggs put into the bator were all fertile- 24 in all. I usually leave it two weeks before collecting eggs from recently separated breeders. I will sometimes still set the eggs in that two week period- but wont keep the babies myself for breeding from.
