Vorwerk Chickens ?

[Ahhmee]

Hi there,
I purchased 3 purebred Vorwerk chicks about 6 months ago to join our flock. As you can see in the pictures attached 1 of them has an array of white through her feathers. Is this normal? I haven’t seen any photos of Vorwerks like this. And the other two (also attached) look normal.

Have I been duped? She is such a sweet chicken and has a loving home regardless of her breed, I was just curious to shy she is soo much different to the others.

Thank you!

It looks like it could be mottling but the odd distribution of patterning and the dilution of gold could suggest vitiligo. It seems weird that the seemingly pure Vorwerks (the others seem to represent their breed) would carry mottling.
