Smokey color gene in chickens?

[MysteryChicken]

Today I slaughtered my first roosters from the Smoky brood. They were 90 days old and weighed around 1450 grams when fasting.
I inspected the roosters that appeared white to me and found smoky-colored feathers on all of them. No black or wild-colored ones. But how can it be that I get dominant white animals again from I^S I^S? It may be that I have two different Smokys. Let's say I^S1 and I^S2. If both alleles are mated, a smoky animal will be born, but also an e+ or Ee. If both, I^S1 and I^S2, complement each other, an I will come again?
It is also surprising why all the wild or black-colored chicks are piebald. My first brood with the original Bress rooster has hatched. All the chicks are white, some with spots in their down. The silver rooster now has 4 white chicks and one black-piebald chick with new hens. One hen is Ii and so the black chick is understandable. All piebalds show smoky color in the white areas. Solid whites are more or less smoky and predominantly white. Some have a smoky tail and a white body with red inclusions.View attachment 4029118

Here he is. He's more blue/gray in tone in reality, but my phone made him look blue/brown.

Perhaps your dominant white Bresse is genetically splash under the white. Then all of his chicks would be blue paint instead of black paint.

That maybe it as well.

You can try to breed a smoky chicken with black animals. I think you can see smoky in mixed breeding. Smoky makes black to a little bit gray.

I know now I hade in my bresse/my chicken F1 one hen heterocygus smoky. Smoky is recessiv against I domminant white. But it's a allel. My original bresse rooster with my smoky henns have only white chicks. Bresse are EE/SS/DbDb/PgPg/WW/idid/kk/bb

I thought for a long time about how my Smoky chickens could have so many spotted chicks. I found an interesting report on American genetics sites. Dutch white-capped hens were mated with colorful Paduans. The chicks were all white-capped and spotted. It's exactly the same as with exchequer and mottled. The reason for this is that two alleles came together. I mated the F1 FFS X Bresse with my Smoky chickens. I don't have any spotted animals in my flock. But there are some mixed-breed ones. This is shown by the white ends of the feathers. So my coarse spotting is also an allele of mottled.

I thought for a long time about how the dominant white chicks could come from a mating of blue chickens.

I remembered my FFG hens. Three were correctly marked, one was blue instead of black and one was, you could say, yellow and white speckled. I looked through all my photos but couldn't find a picture of the FFG. Since the roosters are white, you can't see any color. The FFG rooster only had a few golden splashes on his head. So it might be that this blue is a new allele of dominant white, which is blue in hybrid inheritance and white in homozygous. Then it's understandable why wild-colored and black animals are dying. All are heterozygous for smoky. All white ones too. I'm calling the new color Pastel and suggest the symbol I^P.
I will continue to breed purely with my Asian line of Smokys. I will house the pastel-colored ones separately.
I'm absolutely sure that these are alleles of dominant white.I
I see no splah. It' s not blue.
Same I^D we have dun and khaki
