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

I've been told by 2 different Ermine breeders that this is Smoky popping up in my Ermines. Parent birds Dominant white x Black. Smoky did run in this line that my Ermines came from and was highly culled. Interestingly, I'm about to pair them with my Khaki male. My goal was to make Dun Ermine chicks but now we have Smoky in the mix.

It's not smokey, the bird is probably splash based, or is hiding Autosmal Red which is common, probably not in Ermines that often but it does some strange things to dominant white sometimes.
This boy is a paint, Ermine is a kind of paint.

No there's no blue or splash in this line. The breeder has been breeding it for years. This seems to be happening a lot in the ermine lines with dominant white. That's how smoky was first discovered was in homozygous dominant white. It seems to be somewhat common in the Ermine groups. If it was autosomal red the dominant white in heterozygous form with these Ermines would not be covering or diluting autosomal red.

Autosomal red will show in small patches as well. It's not a one trick poney, it has many faces.

What color they were as chicks will tell you if they actually have smokey. If the chicks were just black, & white then it's not smokey.

I'm no geneticist and I can't even pretend to claim I understand all the technical explanations ... but from a purely layman point of view, those birds are GORGEOUS!
