...and why they wouldn't lay eggs while molting?

I only "feed" my ducks in the winter. They have free access to the feeders, which I fill with whatever is on sale at the feed store. So the percentage varies. In cold weather, I supplement this with scratch grains in the evening. And I give them as much as possible for as long as possible from the garden. Everything from brussels sprouts to winter squashes. But then I am not looking to increase egg production. They can have the break. (I wish I could afford better. But that is the truth. And I am working on growing more of my own feed so I won't have to buy any in in the future.)
My ducks free range during the growing season. They have access to 20 acres but they probably only use a quarter of that. They are particularly fond of drilling in the wet spots under the impact sprinkler. (When I bought this property, it was an old, abused, and weedy hayfield. It is getting better, but the grass still goes dormant in the summer if I don't use some irrigation. And I need the grass to feed the geese. They won't eat anything but lush new growth. Plus, there is nothing like cold deep well water to keep the flock cool on a hot summer day.) The ducks do still get plenty of extras from the garden. They love strawberries! And some scratch grains.
I can't think of any good reason for your ducks to go through repeated moltings like that. Perhaps it is a silly question, but have you checked them for mites?

Birds cannot do both at the same time.
It is either eggs, or new feathers, but NOT both at the same time.
