We feed carrots, potatoes and squash that is grated at least once a week. These veggies are usually fine, just a few dents or tears, but be sure to wash them and check them over before offering them to your birds. Many breeders also offer live food such as mealworms or feeder fish to breeding and growing birds. Both of these are readily available at any pet store. Breeders of Mergansers and other diving ducks often supplement their diets with small kibble dog food, which is high in protein and great for growing ducks.
Drinking water is very important in the digestive process.
Waterers seperate from the swimming water is changed daily. These can be used to administer medications and vitamin supplements. Grit should always be provided. Feeding Your feeding schedule depends on your time, but I prefer to allow waterfowl access to food at all times. This can be done in the various poultry feeders available from poultry suppliers.
