From what I read about the anconas is you actually don't want solid black and their isn't a conformity to it. The black should be broken on the sides, head and underside but no 2 will be alike because their markings are similar to the Holstein cows. Some will get solid coloring but it's an undesirable trait and is recommended not to use in breeding programs. Anconas beaks should also be broken up but again they don't conform so I suppose it's possible to get one with an all black beak. I would assume that's an undesirable trait as well though. I don't know much about magpies. I do know they have similar traits and that their bodies and beaks should also be broken up. Solid color is undesirable and they are just slightly smaller then anconas. I plan on starting a breeding program with my anconas and have been doing loads of research lol. Hopefully I will produce more quality ducks.
I didn't say solid black.
There is a conformity, 10-30° above horizontal and a nicely shaped head is desired.
