The Welsh Harlequin is not an old breed, developed by Leslie Bonnet around 1949 from a color mutation in a flock of Khaki Campbells. John Fugate of Tennesse imported hatching eggs from the Bonnet flock around 1968 and adult stock from Europe in 1982. The vast majority of stock in the United States at this time descended from the 1982 importation. Welsh Harlequins therefore are a "new" and relatively unknown breed. Harlequins are noticeably calmer than Campbells. Harlequin females will incubate their own eggs and they make excellent mothers. Welsh Harlequin ducklings are yellow or buff colored with a slight trace of darker shading at tail tip and behind the eyes.
