The "Ask Anything" to Nicalandia Thread

They, show black in tails, or black, & red in hackles.

Got it Thanks.

A while back I read this article about red shoulder Yokohama's possibly being splash birds:
https://www.feathersite.com/Poultry/CGP/Phoen/ReederRedShGenetics.html
So I bred a Yokohama to a cemani to see what I'd get and sure enough, the chick was blue. As it's growing it's developed a few random black feathers as well. However I'm not understanding everything I read in that article and I'm wondering if anyone knows more about how the blue is not consistent with the Bl gene?

Its likely just Blue or an allelic mutation of Blue.

Lost my notifications so I'm making a post.

Not a question, really, but an interesting phenomenon in one of my current chicks.

Every other Australorp X California White that inherited the dominant white has been like the current white cockerel, lightly flecked with small specks of black like their mothers.

Males from that cross will inherit the Barring gene from their Dame adding an additional diluting effect. Females can't inherit Barring from their dame so the are Paint proper

Oh!

I was mistaken in thinking that was a sexlinked cross then.

This is the first white female I've had from the cross. All the other female chicks from the CW girls have been black.

The gender split is just a coincidence. The Dominant White gene is not on the sex chromosomes, so black vs. white from this cross is not a sex-linked trait.

In it he says:
The dilution gene(s), when outcrossed to a non-diluted eumelanin, becomes a blue gray in the female in all eumelanin areas and is blue gray in the male with the tail growing out white at the base, with this factor often increasing over time. This is consistently the effect seen in F1 outcrosses of RSY to all the alternate alleles, when no form of eumelanin dilution is present.

This would then seem to indicate that Bl is present and perhaps the RSY is a "splash," as the f12 in outcross is not consistent with I/I+ Bl/bl+. However, the behavior of this "blue" appearing factor is not consistent with the gene Bl.

So I bred a Yokohama to a cemani to see what I'd get and sure enough, the chick was blue. As it's growing it's developed a few random black feathers as well. However I'm not understanding everything I read in that article and I'm wondering if anyone knows more about how the blue is not consistent with the Bl gene?

I have a bantam roo from a blue mottled to blue mottled breeding that has similar markings/coloration to the RSY. Could the the color genes be similar enough to try breeding together to try to get bantam RSY?

Now I want to order Yokos to experiment with.

Two different chicks
Recessive White or Splash?

Same dad (OE, blue with silver barring), mom could be anything out on the yard. I have a hen that was hatched from a white hen and she ended up Blue Wheaten.

Is dominant white a possibly too?

Better pictures.

Due to the pattern of blue, I would say the chick is blue rather than splash, and something else is causing the white feathers.

I meant that I had thought that the California Whites were a sexlinked cross.

I looked it up and discovered that the breeds were reversed from what I'd thought. California Grey males over Leghorn females where I'd thought it was the other way around.

Will keep updating.

Oh, that makes sense. You were talking about whether the California Whites have barring or not (so they can pass it to their chicks or not).

I have read that many White Leghorns have barring too, so the California White hens might have barring no matter which way the cross was done.
