For people who like to keep poultry, ducks offer certain advantages over hens. Ducks are immune to some common diseases found in hens and are less vulnerable to others. Some breeds of duck produce bigger eggs than hens. In addition, ducks lay eggs over a longer season than do hens.

Poultry keepers with gardens have less to worry about if they keep ducks rather than hens because the former are less apt to dig up plants and destroy roots. While both hens and ducks benefit the garden by eating pests, hens are known to damage herb and grass beds. Ducks, on the other hand, will search for insects and snails more carefully. Only very delicate plans are at risk from the broad, webbed feet of ducks.

Like all waterbirds, ducks need access to water, and duck keepers typically provide this by building a pond. Something this large is not absolutely necessary, however; ducks need only to be able to dip their heads in the water to keep their nostrils clean. If a pond is provided, though, it is important to keep ducklings away from it until they are old enough to withstand the cool temperature of the water - about eight weeks.
