I am new here, but what made me want to post is that we recently had 6 ducklings, 5 of which are welsh harlequin (male) and blue swedish (female) crosses. One turned out to be what could be called a brown swedish (if there was such a thing). He/she is all brown with a white bib. Another of these crosses is a black swedish with some black spots on his bib. Beautiful ducks. But definitely the result of crossbreeding because our 2 males are welshies.
