Clarification on gender and maybe a guess at breed?

[NatJ]

If there is no visual barring on any of the males, the chick in question is a sex-linked male.

I was getting there. You always gotta steal my thunder.

Yes, he’s a sexlinked male.

If we're discussing who said it first, I think that would be me:

With a Barred Plymouth Rock mother, you might have a sexlink there, depending on what genes the father has. If the father does NOT have the gene for white barring, then the barred chick would have to be a male. But if the father has, or might have, white barring, then the white barring on this chick does not tell us what sex it is.

And, after OP posted photos of the roosters:

I don't think I see barring on any of the roosters (hard to tell on the palest few).
But if the father is not-barred, then the barred chick must be a male because of coloring (in addition to other ways of telling).
