Rustic Rock? What is this cross?

[Too Fast]

We got 3 Rustic Rock chics, they seem happy at 5 weeks old. They are more fiesty than the Cinnamon Queens.

I don’t think so.

You're absolutely right. You can't get a barred pullet from a solid roo sire. The barring allele is only on the male X chromosome, why it is so easily used for sex linkage with a solid colored sire. But a Rustic Rock pullet is barred,

it probably is the same thing as a rustic rambler. I have two rustic rock chicks from TSC as well! good luck!

Can't be. Any barred hen must have a barred or cuckoo sire. Rustic Ramblers have solid BCM sires, perhaps a Cuckoo Marans?

I think I read somewhere that they were experimenting with a RHODE Island Red over Barred Rock cross. Should be a good cross!

That still wouldn't get barring on the hens. XY chromosomes with a solid sire won't have a barred X for the daughters, since the mother gives her barred X ONLY to her sons. That cross sounds like an F2 cross back to the RIR?

I recently purchased a few pullets that were labeled Rustic Rocks. They are small black chicks with a yellow dot on top of their head. I cant seem to find any information about this breed or cross on google. I was thinking maybe Maran and Barred Rock cross. Does anyone know what cross this consists of?

For those who purchased rustic rocks at TSC, does anyone else think they might have gotten a rooster? Are they sex linked?

TSC's advertising image shows a barred hen very similar to a Barred Plymouth Rock, so they must have a homozygous barred father giving both daughters and sons each his Z-linked barring allele (otherwise the daughters would not have any barring since even barred mothers only give the barring allele to their Z-chromosome sons.) They seem to be keeping it secret, but a spot should be on both genders' heads to indicate the barring. If they are a sex linked cross, perhaps the size and placement of the spot is the indicator?
