Auto-Sexing vs. Sex Linking

[Prince and Pavo]

I've done purebred sex-linked Sussex and if I crossed my Barnevelders correctly I can hatch sex-linked.

Buff sussex rooster over Light sussex hens.
Gold laced Barnevelder rooster over Silver laced hens.

That’s very interesting! Thanks for sharing!

Okay thanks for the info! Can you give me an example of a purebred sex-link? How would it be purebred if the characteristic only lasts one generation?

Solid cochin over barred cochin. Solid Plymouth rock over barred Plymouth rock. Partridge over silver Partridge silkie

Is it possible to build an auto-sexing breed off of the color pattern Red Pyle?​

I’d be curious to find out. It looks like the down is pretty pale and lacks much patterning though.

 

[The Moonshiner]

I wouldn't see how you could. I didn't think they had any pattern when they hatch.

The Yokohama looks like a red Pyle bird and has patterned chicks. So what’s the difference between the Yokohama and the average red Pyle bird (other then the obvious mottling genes)

Yokohama is a red silver mille fluer color.
I don’t know why red pyle has yellow chicks but it does.
It is hypothesized that the white coloring is Yokohama is caused by two blue genes (splash) rather than dominant white as in red pyle so perhaps the dominant white in red pyle overwhelms the pattern in the chick down while the splash does not.
It is thought that otherwise the dilution that causes white in Yokohama is specific to that breed.

Really cool, so in theory if you breed a black chicken to a Yokohama you would get blue, black and splash? Or some combination of the those colors?
Adding the baring gene to a red pyle would only get expressed in the red feathering and I can see that it won't work. I had hoped that some lines of red pyle would have a chick pattern similar to the Yokohamas. Yokohama chicks look like wild type but lighter in color.

You would just get blue. Plus red silver leakage. In theory.
