mine get duck/goose breeder pellets-they aren't for eating though. Waterfowl have a higher need for niacin than hens and while they might get that through foraging in the summer, I prefer to give them a specific diet. I also had ducklings that got splay leg from normal chick crumb (which righted itself with brewer's yeast and then duck grower pellets) so would only use duck starter too from now on. I also give everyone some micronised flakes (barley, maize and peas) in the winter daily and they do well on it.
