A mutation! Stripes in a black bird

[Cyprus]

her blue is very irregular but that is common, blues often are not perfectly solid. by that I mean even shade. she is obviously 100% blue with no leakage.

Clearly.
I still can't fathom how one copy of the mottling gene is doing this.

I believe its an expression of mottling as there are no leaky blacks in this chicken's entire family that I know of or the breeders know of. Including it's other cross siblings.
Second reason is that mottling when heterozygous does leak pretty commonly. Some of the siblings have 1-2 mottled feathers on their foot feathers, primary feathers and upper breast. Also the way mottling works is by delaying the flow of melanin into the feather as it grows and looking at individual feathers it looks like a similar thing has happened.
Third reason is that mottling mutations are one of the more common ones. exchequer leghorns and white yokohama chickens are both examples of mottling mutating. Or at the very least another gene acting on mottling to change its expression.

Excuse me? Did I elect you as my voice? I think not.

If you remember my post, I told you I've seen this before.

If I have to prove that stripe's has a black hackle then you have to prove youve seen it before.

Let's see what @The Moonshiner @AMERAUCANAS4REAL @nicalandia and @Egghead_Jr think.

I noticed that it has a black hackle after seeing the other images. I'm going to wait for wiser souls to show up.

I also just noticed that you're in Australia. The Silkies and d'Uccles in AU don't have exactly the same genetics as the ones in the US.
That makes it much harder to tell who's right. I'm guessing you've been studying genetics that pertain more to Australian stock?

I study all of it, australia, overseas, I even study genetics of dogs, cats, cattle, rabbits, horses, mice, sheep ect. Genetics is my hobby/passion.
Supposedly Winslow could be partridge based (this is only mentioned by one source) with just melanizer after melanizer layered on top and possibly some form of recessive black. I know he has charcoal and Wilma does not as her blue chicks have darker hackles. Wilma is still very likely to be Extended Black. My goal in the cross is to have Extended Black with all the melanizers stacked on top making them ultra black like ayam cemani. The point being is that there is still no cracks to let any ground colour leak through. If I do see ground colour leakage I expect to see in in my F2s and will happily report what shows up.

Well, I know nothing of genetics - like at all. Genetics dumb, I am. But I will say it's a pretty bird you've got there, regardless of how the genes interacted to make it pretty.

oh thankyou! I like the little guy too. The stripes have been spreading I think as it grows so maybe it will have stripes all over one day. But we will just have to wait.

If you wanted a black melanistic bird, why didn't you just breed an AC to a Silkie? Why bring in the d'Uccle blood?
