A mutation! Stripes in a black bird

[Amer]

To be honest it looks like silver leakage on the black pullet, I've seen white lacing on Black breast before but it looks much better.

This happens on Birchen and Pseudo birchen pullets(Extended black heterozygotes)

That's what I thought as well. I think that the leakage was probably hidden by the mother.

I agree.

The feathers sorta look like this and they are only on it's chest. Its mother is a blue mottled belgian d'uccle, and its father is a black silkie. There are also 4 others out of the same mother/father who dont have anything like this.
Besides that the father has also been crossed to another black mottled belgian d'uccle and out of 17 of them none have anything more that one or two mottled feathers.

Has anyone else seen this or is it likely a mutation? Im assuming its a mutation of the mottling gene so Im going to keep it in the flock and see if it will pass the variation to its own chick.

Solid black everywhere else:

The mother:

The father:

And I study all genetics. Not just d'Uccle's. Im confident because there is no leakage in either side of the family. Nothing there to let the ground colour leak through. Also even if it was what would the odds be? 100% white leakage would have to mean silver and to have a white breast it would have to be a Partridge or wheaten hen with silver and ar/ar which is unlikely considering d'uccle are usually gold with Ar+/Ar+. Not to mention that ive hatched 29 others out of the same father and not a single one has anything like it. Im honestly not sure why you are so confident its ground colour leakage.

I'm not sure if it's the picture, but it definitely looks like the father has silver leakage in his hackles.

I think I know barley anything about genetics, but this seems like a pattern I have seen commonly on mixed birds... And, I have to say, that silkie is not even kinda close to show quaility, and if they paid alot for him, they got ripped off!

The silkie looks much closer to pet quality than show quality.

Stripes has 29 brothers and sisters with nothing like it and Ive never seen anything like it and neither has cyprus. its a theory. Im going to do crosses later to see if I can get it breeding true or if there is more to it.

Since the father has so little leakage, and I'm assuming you bred him to solid black/blue/splash hens, it probably just doesn't show up very much.


A few pictures of chickens with similar leakage I found on the internet:

I see white on the top of the head and the hackle.

I also see silver in the hackle. It just hasn't shown up yet since the chick's so young.
