Crested ducks in at least 3 hatchery sites just call them white crested or blk crested. I always associated them with say Pekin or Swedish etc not a breed of it's own but it is.
There is alot of concern and controversy about Crested and especially breeding 2 crested together. On BYC we have seen heart ache and triumph with this breed.
What a gorgeous Sunflower, Not one I have been able to grow here.
I've seen crested in those breeds too PotatoWaffles. Just about any breed but Muscvoy. I think I saw on a hatchery web site they just offered Crested with no breed name at the end.
