Welsh Harlequins not laying for several months?

[LuckiestMamaof3]

Hello!
I have five welsh harlequins (3 female, two drakes) that I got as babies in May of 2021. They have been prolific layers, and I think all three females started to brood this past spring/summer (2022), at various times, but we ended up collecting all the eggs when we found them. Anyway, it has now been about 3 months since I have seen a duck egg, and I think they are not laying at all (vs hiding them). We have a chicken coop and a duck coop next to each other, with fencing around an open run. We are a bit crowded right now and need to get rid of some of our chickens, so I wonder if that could be a factor?
Anyone have any thoughts as to why they are not laying?

Likely molting and winter break

Start offering oyster shell so when they start back laying they will have sufficient calcium to lay strong shelled eggs. Won’t be long now since days will gradually get longer.
