Recreating the 55 flowery chicken coloration

[Floof]

I'm working towards recreating the 55 flowery autosexing coloration. Last spring I crossed my speckled sussex hens with my single barred EE rooster and my barred splash ameraucana (technically an EE, I know). From those, I hatched 4 single comb and 1 pea comb hens and 1 very large single comb male all with a single dose of barring. They have all started laying and I am getting 1 blue egg, 2 green eggs, and 2 brown eggs.

My plan is to hatch out as many chick's as I can this spring and select for mottled and barred. My understanding is that will yield the coloration for the 55 flowery and then I can breed them together to reproduce the coloration reliably. Do I have that right?

55 flowery also includes the gold duckwing coloration. If you have any cream legbars, they have duckwing and barring so could help with your project.

That's news to me
What part of the phenotype is that responsible for?

Here’s a 55 flowery hen:

Here’s a brown leghorn:

Brown leghorns are gold duckwing. Imagine the 55 flowery without the white, and you have a brown leghorn. Since the 55 flowery roosters are mostly white, it’s hard to show their phenotype.

I'm sourcing very old threads that nicalandia participated in for reference. I really respect Nic and generally don't question his knowledge.

"Genetic make up of 55 Flowery pattern is e+/e+, mo/mo, s+/s+ (gold based) B/B(B/- for females)

Genetic Make up for the Speckled pattern, e+/e+ mo/mo s+/s+ b+/b+(b+/- for females) Co/Co, Mh/Mh"

He goes on to say that the source for barring isn't super important and lists a couple viable breeds. He doesn't list brown leghorns at all. I'm only looking for the autosexing coloration for this project, not body conformation or egg color. I will still end up with white males and barred mottled females, won't I?

Brown leghorns aren’t barred, which I assume is why he didn’t list them. I don’t know for sure if you would still end up with an autosexing adult. Many autosexing breeds use either a gold duckwing or gold/red columbian base color (with barring). However, black with barring can be autosexing, too. If you don’t want to do the exact genetic makeup of a 55 flowery leghorn, there’s no issue with that, I just wanted to point out the difference.

I think the SS has those genes covered. Does anyone know, is it just the double dose of barring and double dose of mottling that gives the white male? There isn't another gene at play?

Following as I also am wanting recreate the 55 flowery. My understanding is it was derived from crossing light brown leghorns with white leghorns. Did Martin Silverudd have silver and barring in his brown leghorns? Or did he use other similar breeds to introduce those genes? What specific genes cause the dramatic difference in coloration of the rooster and hen?

Genetic make up of 55 Flowery pattern is e+/e+, mo/mo, s+/s+ (gold based) B/B(B/- for females). That means wild type down color, double dose of mottling, and barring. The 55s come in gold and silver so I don't know that it's important that the originals were gold base... the reason the females are darker is that they only carry one dose of barring but the males carry 2 doses of barring (thick barring on top of the mottling makes them nearly white).
