Genetic Difference- Mille Fluer & Speckled Sussex? WHAT's missing?

[dldolan]

What will I get if I do this:
SS hen x Splash Marans roo

Thanks,
Dawn

SS hen x Splash Marans roo = blue F1 hybrids

Male F1 blue hybrid x SS hen = some BC2 blue mille fleur and other colors ( hatch 20 or more chicks)

Male BC2 blue mille fleur x SS hen= good looking blue mille fleur and other colors ( hatch 20 or so)

Thanks, Tim! I appreciate your help.

What about crossing an actual porcelain bantams to an LF (sussex or otherwise)? Or is it a bad idea to cross LF and bantams to introduce colours/patterns between the two?

My guess is that it would be better to recreate the color using LF if you can. As long as it might take to do it that way, I think you might battle the problems associated with, say, using a Porcelain D'Uccle even longer.

By problems, do you mean fixing type, or is there something else I don't know about?

I have made the speckled sussex x light sussex cross and then crossed the F1's to get some F2's that are golden mille fleur large fowl sussex. If I had used a coronation I would have made a few porcelain large fowl and in fact that is my next step. Here are two of my Golden Mille Fleur pullets from 2012. They lost the mahogany gene along the way. Also my light sussex are wheaton based and the speckleds are wild type, my gold mille fleurs are of several types. The ones with the cleanest ground color are wheaten and the ones with wild type have more pattern and peppering. My goal is to breed toward a wheaten base for nice clear ground color. Pullet 2 has more white in her final plumage, she is also about 25 percent larger than pullet 1.

Most people prefer the pattern on 1 but I am using pullet 2 because of her size and type are more sussex. She is 7+ pounds and will easily be 8 as a hen. The cockerel is not as large as I had hoped, His brother I am keeping for breeding is a large speckled sussex (with Mahogany) This boy in the picture may be heterozygous for Mahogany or else he is not carrying it. Heterozygous for mahogany is shown in the last photo (she is the F1 cross of the speckled and the light, and mother to these mille fleur)

This is a fun project

Nice birds! I gave up this project and focused on my Splash Marans and Olive egger project, but it was fun to reread this thread and see your birds, Andy! (BTW, splash Marans roo x wheaten Ameraucana hen make EXCELLENT colored green eggs!!!). The feather color genetics fascinate me! And who doesn't loved pretty eggs as a by-product?? . Cheers, Dawn

Hi Andy! I've PM'ed you privately with genetics questions related to your project, but I wanted to post this question publicly, as it might help others.

Okay, basically I'm trying to make something like your Mille Sussex (but with lots of white and yellow legs, but that's not important right now.) I am also adding the Dun gene for interest, but that is just a simple dominant gene, so nothing I can't understand there.

However, I am still struggling with understanding the Silver gene and how it works? It is the whole "sex linked" colors thing that throws me off every time . . .

Here are two of my newest chicks. I *think* rooster but maybe you can help figure it out?




Sorry for the condition, lots of feather-pecking in that pen even with supplement protein.

I believe this is the pen they were hatched from:


Dad is an enormous Buff Sussex from a breeder in Colorado. Mom is a "Cinnamon Sussex" from another breeder's project eggs that I ordered from Ebay, and has the Dun tail and neck feathering. This is the only hen like this in the pen, so obviously she's the mom.

My question is, I would like to breed one of these roosters (they are roos, right?) to Speckled Sussex hens.

What I'd like to know is: What chicks will turn out Silver? Will I get any Buffs? I'm trying to get something without Silver, but with Dun, and Mottling. Ideally, I'd like a Buff Mottled with Dun, but even a Mahogany Mottled where the black has been replaced with Dun would be interesting, and a step in the right direction for my program!
