Is this a sex-linked chick?

[Fluster Cluck Acres]

I hatched an egg from a this barred 1/2 Bielefelder hen (other half is SLW & BCM).

The father is a BCM rooster.

The chick’s down is solid black. Does this mean she’s a she? I think a male chick would have to be barred and therefore have a head spot? Or would the mixing of breeds change the rules about being able to visually identify the barring? This is the only chick I have from this pairing right now so I can’t make any comparisons.

Mixing the breeds doesn't change the rules of genetics. That is indeed a female. As you said, sons would inherit the barring gene.

That's a pretty hen by the way.
