[5][6][4][7][8][9] It was developed at Uley, in Gloucestershire, England, at the turn of the 20th century; being introduced to the public in 1898 [10] and the Khaki variety in 1901.

The Khaki Campbell drake is mostly khaki-coloured with a darker head usually olive green lacking the white ring of its Mallard ancestors.

When provided a moderate "duck conscious" environment to live in they will lay a more than modest number of eggs per week.

Most brooding instinct has been selectively bred against in exchange for prolific egg laying ability in this breed.

Mechanical incubators or broody chickens are used to hatch out Campbell ducklings when ducks are not present in the process.
