Welsh Harlequin ducks started as a mutation of the khaki campbell. Depending on where you got the ducklings it could be an outcross, an off type or a mix up. My bet is on outcross.
I know when I got my welsh Harlequin there was one of the twenty that was slightly different but they shouldnt be this different.
