Blue/green laying sex linked

[newhenintown]

Because the OP wants sex linked offspring. Any non-white, non-barred male crossed with a barred female will result in sex links. Male chicks will have a white head spot while female chicks will be solid in color.

Very interesting seeing as how my EE cockerel that is crossed with something barred had a white spot on the top of his head when he was a little chick. He is the only one that I have that looks like this and they all supposedly came from the same hatch.

Sounds like they are sex linked. If they are, he would be the only one with the barred gene, if the rest were pullets. Or the male had a barred gene and this is the only one that inherited it. It would be a 50/50 chance.

So just to clarify, a male ameraucana over a California grey would produce sex linked, 100% blue laying chicks?
Yes.

And if I crossed an olive egger with an amerauncana that would produce 50% green layers and 50% blue layers?
Yes. There's always a tiny chance of a brown layer but it's unlikely.

And assuming all of that is correct, how would I go about getting a barred olive egger?
Most that I know of use Crested Cream Legbars and Gold Cuckoo or Cuckoo Marans.

And I know I am opening a can of worms, but how does one go about breeding autosexing?

Most autosexing breeds have sex-linked barring(B), the duckwing pattern (e+, "chipmunk" patterned chicks), and a gold base (s).

The recipe for a plain ol' Legbar is:
Gen P: Brown Leghorn male x Barred Rock female
Retain F1 males (they are split to barring, duckwing, and gold). Cross to Brown Leghorn females.
Retain F2 males and females that show barring and gold duckwing coloring. Cross together.
Retain F3 barred females but only retain males that show double factor barring. They will be a lighter color than single factor males. Offspring from this cross will all be autosexing.
