Hi All, making a thread because I hadn't seen this particular cross asked before and figured I can't be the only one who is curious!!
So I have a Fawn & White Runner Drake (male) and a Black Runner duck (female). all I know about their genetics is that the American f&w has the double blue dilution (I think?) and that black is a dominant "mask" so the duck could be hiding any sort of funny color genetics behind that extended black!
I used the eend calculator and got that the offspring would be blue, diluted blue, and lavender (all pied) for both male and female ducklings. Are there any sex-linked traits in this cross? where are the ones with this like even red tone coming from (they have areas of red where there doesn't seem to be any clear demarcation between yellow (white) fuzz and this rufous reddish tint)
So I went to hatch 10 eggs. all were fertile and only one didn't make it. I ended up with 9 chicks of varying colors, all pied from the runner gene, but not "runner pattern" per se. All ducks had splashes of black OR gray (!) on their legs and beaks, but in specific patterns: every duck had at least the middle toe black/gray and had some level of "pants" (meaning the black/gray looked like they were wearing capris lol).
For coloring, 3 ducklings appear to be dark gray (blue?), 3 appear to be a light gray (lavender? diluted blue?), and 3 are almost a dusky red/brown? They all look drastically different from their fawn &white father, who at their age was COMPLETELY yellow save for one small light mark on the top of his head! also their pied color pattern leaves them all with a distinct stripe of white down their belly, where a runner would have their fawn color on the abdomen, these have completely yellow (white) bellies that continues from their neck all the way down their underside!
I know this is probably a relatively standard cross that's pretty common, but since I had never seen anyone ask about the f&w male x black female I figured I'd put it out there!
ALSO the black duck mom isn't bibbed per se but does have a small patch of white right on her breast it is just like the smallest dot and she's had it since birth
Here are the babies:
Here's dear old mom and dad as babies and adults (the black duck's beak is now a deep blue/gray, she grew out of the olive green beak!):
