Unexpected Blue chicks from a porcelain rooster

[Amer]

So Fawn and dun are basically two names for the same gene? Like lavender and self blue?

Chocolate, fawn, and dun are used for the same phenotype, yes, but the gene is always dun.
And yeah, lavender and self blue are also used for the same phenotype, but the gene is always lavender.

I thought I'd add some pictures. Now that they are out of the coop, I think I can see more of a brown tint.

The white one (mother is the buff laced sebright) has brown on its crown.

I have another male and a female that hatched out. He hatched with the same darker color as his brother and she is the lighter grayish brown.
I'm wondering if they might be sex-linked?
@Amer is this possible? Thanks in advance

I wan to update with a couple of photos of this girl after her first molt.
She is from the oegb fawn silver duckwing over black mottled cochin.

Her pattern isn't consistent but the coloring is really beautiful in the sunlight.

Wow! It’s so cool to see that edging! Reminds me of laced blues.

The mottling gene causes the feather to have eumelanin around the white mottle (if the bird has eumelanin to work with, hence why red mottled birds don't have it.)
Because our idea of mottling is black with white spots, many think that all mottling does is make white spots, not white surrounded by black.
I don't know why it does that, but it does.
It's why mottled gold columbian can be mille fluer even if the bird isn't genetically spangled.
I wouldn't have expected it to deposit the same darker mottle on chocolate but here we are.
