Recreating the 55 flowery chicken coloration

[Floof]

I ran my F1 hens with my f1 rooster but hadn't culled out my EE roosters until last week. I still did a test hatch to make sure my incubator was up and running. From these chick's, it looks like I have 1 female F2, 1 male F2, and then a handful of sexlinks. I still have more in the incubator that might hatch tonight but I'll admit my incubator parameters sucked this time around and I might not get too many more. What do you guys think about the 2 on the bottom here?

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).

Thank you for the details. There is a paper I read that stated that silverudd bread the dominant white out of the WL. How is this possible?

Dominant white is easy to breed out, it’s just two genes. It would just have to be replaced with recessive white.

The good news is, Speckled Sussex are duckwing based like brown Leghorn.
The bad news: 55 Flowery's may have a different type of special Leghorn barring
But this is all theoretical

Dominant white is easy to breed out, it’s just two genes. It would just have to be replaced with recessive white.

So first generation would all carry one copy of dominant white but if you bred them together you would get 25% with two copies of dominant white , 50% with one copy and 25% with no dominant white, is that right?

Yes, if you were breeding dominant white x a bird without the gene in the first generation

Yes

Thank you for the replies.

Ok so back to my project

I had a few more hatch out and I'm thinking my first light colored fluffy butt was actually a splash EE from one of my culled roosters. Take a look at the photo and give me your thoughts. Do these two look like they have the barring gene at all?? I'm used to looking for the headspot.

If the hen you crossed to was black or black barred, then a splash EE cross would result in a blue chick. This chick looks silver(?)
