Chocolate gene and sexlinkage - can someone explain what I just hatched?

She looks similar to the hen in this post, which is apparently mauve (unless I’m misreading it):

I guess that's it then...

Is it possible your rooster isn't black at all and is instead very dark dun?

He looks awfully black but honestly that is the only plausible conclusion I'm able to come to at this time. Nothing else makes any sense at all. There is no way I get chocolate or mauve males from a black split to chocolate rooster. It's not possible unless we don't fully understand this gene

Now I'm looking at my other two chicks hatched from a different rooster but same breeder, and different hen that I assumed was mauve and either darker mauve or blue and wondering if maybe they are dun too parents shown in photos with the two silkie chicks I've hatched too

Mauve is Sex-Link chocolate with blue. But again they should only be females in that case, no males. But I have males

View attachment 4103784This hen doesn’t look blue to me, she could be mauve or dun? If she has the chocolate gene and the rooster carries it, they could produce chocolate sons.

They are blue with partridge underneath and have leakage due to that. Their father was black and white mottled. I didn't hatch them but saw the flock they did come from in person and none of the chicks were out of place according to parentage. This picture was taken in the dark. Also- they hatch definitely blue and some black chicks too not just the ones in question. I also got partridge and some kind of chocolate/mauve/dun partridge too

She does look blue to me...
Mauve tends to be lighter.

This is what I was thinking too..... then I
started looking through Internet photos and now im not so sure. I know the hens came from a BBS pen and the rooster was a black and white mottled roo with leakage that I am assuming was due to partridge being in the make-up. But as we all know black males can indeed be carriers of the chocolate Sex-Link gene.

To further complicate this insanity - I contacted the breeder the roosters came from and she did in fact have dun/khaki birds at one time, a long time ago. She said none of them were retained...... But

Let's say the hens are mauve and not blue bred to a chocolate Sex-Link split roo what would I get? Then what about if the hen is mauve and the rooster is actually dun?

Did anyone see parentage of the birds in this post? I'm reading it as they were asking for help on breeding the color

Yes, I know what mauve is. If you have a hen with the chocolate gene (like mauve) and you cross to a rooster carrying one chocolate gene, you can get males with two chocolate genes.

If the rooster has no chocolate gene you wouldn’t get any chocolates at all, only carriers. If the hen is mauve and the rooster is dun, 25% of the chicks would be black, 25% will be blue, 25% will be dun, and 25% will be blue dun (which I think is called platinum).

I had never heard of platinum. Now I will have to look that up

I think my next question is - is there any way to actually figure out what genes were at play here? Meaning is the hen blue or mauve? Is the rooster split to chocolate or actually dun? Are there disqualifying genes that would eliminate the possibility of either, meaning if there are other genes on the same locus that can't express at the same time or some thing along those lines because I did get other things from this hatch not just the chocolate/mauve/dun colors.

Um
If you cross the rooster with a different hen and get sexlinked chicks (or not) there's your answers. I don't think both chocolate and dun are at play here but clearly one is.
