Khaki Campbell ducks seldom hatch out others' young; however, in very communal situations do hatch large broods together. Most brooding behavior has been sacrificed in exchange for prolific egg laying ability in this breed. The ducks, when raised by hand, are not usually defensive of their eggs or nests, making collection of eggs very easy. Mechanical incubators or broody chickens are used to hatch out Khaki Campbell ducklings when ducks are not present in the process. Incubation takes approximately 23 to 28 days for a Khaki Campbell duckling to hatch and eggs need to be inspected for ducklings that have not emerged
