Duck color genetics

[Appyfoot]

A couple years ago someone helped me out with a really really helpful chart for ancona color genetics. (I was specifically looking for magnified genetics but that study was very very helpful)
I am hoping we can do it again!
I saw somebody who had a white call duck with a black beak. What words am I looking for to buy one of these or what do I need to combine to breed one myself?

The colors I know of that can be white with black bills are,
1. Splash ducks, which have a 25% chance to be produced from two Blue ducks. They may be all-white or near-white.
2. Black / Blue / Chocolate ducks, who all turn white as they age!

Okay so 2 things
1) that is concerning I have a chocolate bibbex then I did not know she was going to whiten as she aged what age can I expect that to start happening
2) could I achieve the same effect by breeding together to Blue bibbed thus theoretically getting a splash/white bibbed?

1. I’ve seen ducks who’ll start turning white in their first year, but it takes many years for them to reach full-white.
2. I don’t see why not.

Bad pictures since they didn't want to be photographed. This Ancona girl (right) has a grey beak, mostly white with some light grey spots. Next to her is plain black and white drake. Other drake is his son, a dark dark chocolate so he carries brown. Pictured drake also had a tricolor sibling. Her mom refused to be photoed. She is mostly white with a few light brown spots and speckled beak.

Edit: pictured duck is 1 year old.
