My ducks seem to molt for quite awhile. My drake's been molting actively for 3 weeks, and he's very slowly regrowing feathers. He still doesn't have his drake curl back.
One of my females started molting 2 weeks ago, and she's still leaving piles of feathers wherever she goes. You never realize how small a duck's wing actually is until they're molting. It's like a little stub!
Just hard to say some of your girls may lay again before the year is up then again they may not till spring. That is something we don't know for sure. Today from 6 ducks I got 3 eggs last week one day I got 6.
