When i bought my ducks, they didn't eat for almost a week. I think they were shocked from being transported and removed from their home. The breeder said just to give them time and try to leave them alone and not stress them out. After several days, they finally started eating. Dried mealworms and dried tiny shrimp are very good ways to entice them to eat. You can buy them at a lot of pet stores, online at chewy, etc. The brand i buy right now is called Happy Hens. They sell meal worms and also a mixture of oats, corn, and mealworms. I've tried both and my duck likes them as a topping with the Mazuri food.
