Odd coloring in Dominique feathers

[Jaime918]

I noticed yesterday in 2 of my girls a noticable greenish-blue hue in her wings. They are supposed to be heritage bloodlines. They are 19 weeks I believe.

What could cause this?

*Not pure bloodlines?

*Barred rock mixed in (I noticed it happens in BR when I Google)?

*Possibility with heritage lines?

 I'm just so thrown as to where the coloring could come from.

This girl has more than the other, the photo is of her wing.

Green sheen is caused by autosomal red, even though she might be too melanized to express red in her surface plumage.
It can be bred out for that off black off white that many prefer in Dominiques.

The green sheen is actually due to over-melanization on the black bars on barred breeds, it's more common on females because they only have one copy of the sex linked barring mutation.

There are Silver based birds with nice green sheen on their black feathers.

I know they’re silver based, but isn’t autosomal red separate?

Yes, but Autosomal red is not responsible for the green sheen on black feathers.
