Purina makes a duck specific pelleted feed that I've heard good things about, but my stinkers won't eat pellets. I think it can be fed from hatch through adulthood. I feed a little later crumble to my duck hens during laying season in addition to the FR crumbles, but other than that they eat only Purina FR. And the occasional mealworm treat, lol.Do they sell it in a pellet form for when they get bigger? Do you feed something different during laying season?
I give some cracked corn in the winter to help my birds stay warm, but only a couple handfuls in the evening. It gets below -20 here most nights in the winter, so they need help at times.
