Ducks are an entertaining and relatively low-maintenance addition to any homestead. They may make a mess with mud and water, but they are generally charming, hardy against the elements, and prolific layers of rich, delicious eggs. Once you’ve decided to raise ducks and procured your perfect breed, it’s time to set up a home for your feathered friends. How many square feet do you need per duck? The size of the structure will ultimately depend on how many ducks you have.
