I have three 11-mo old runner ducks, all laying. I am adding three more in the next month (still in brooder inside). My first three are eating Mazuri food - mostly layer feed but sometimes mixed with maintenance feed. They free feed throughout the day and usually finish all their food, combined with foraging in their pasture/enclosure (plus treats, of course). Any thoughts on food when the younger three are integrated in the coming weeks? Is it okay for them to eat the layer feed so far before laying?
