Do you have any photos

They are all little chunks. And they can only be this mix as the only lavender roo I have is Ameraucana and only lavender hens are Orpingtons.

There so cute

How does the autosexing of biefelders and 55 flowery hens work?

I mean; how is it that males are so much lighter? I assume it’s barring, but why would the barring lighten the whole body of males as chicks? I thought all it did was add a headspot. I know 55 flowery have mottling too, but biefelders don’t, and the males are still much lighter in the body as chicks.

Males have two copies of sex linked barring. Two copies dilutes both Pheomelanin and Eumelanin. Thats why males are usually lighter.

On black-based chicks, barring adds a headspot to both genders. One vs. two copies of the barring gene can change the size of the headspot (two copies = bigger spot = male), also makes a difference in how dark the legs are (two copies = lighter legs = males).

On e+ chicks (wild-type, chipmunk stripes) barring seems to put a headspot only when there are two copies (males), and it also lightens the entire body when there are two copies (males).

I don't have a good explanation for "why" it behaves this way, but it is fairly clear that it does have a dose effect (two copies makes something lighter than one copy does), and that it looks different depending on what the base color of the chick is.

I don't know what it does on wheaten, partridge, or birchen.

Thank you, both of you.

There is no Headspot on Wheaten, but males are a shade lighter than females.

On eb and ER the effect is the same, Lighter males with larger undefined Headspot that extends to the back of the head.

Wheaten based Hambars

Golden cuckoo Maran chicks ER Barred.

I would like to add that for the Autosexing to be possible on Wheaten it must be on a gold base And Columbian restricted. If any of those components is missing then Wheaten can not be sexed at hatch at all using down color. For example Delaware chicks. They are all yellow colored because of Silver.

oh neat! i know nothing of genetics but love seeing what random colors and patterns i get from crossing my purebreeds. What would i get from crossing a black jersey giant rooster with a lavender orphington hen? Would the chances theyll be as large as the dad?

They are usually the average of both parent breed plus about 10% heterosis.
