Blue/green laying sex linked

[JenniferDuBay]

What would be the easiest recipe to get blue/green eggs with sex linked colors? Additionally I would like them to be a heavy layer, preferably of large eggs.

Do you want sexlinks (sexable with F1 only) or autosexing (sexable with every generation)?

If you want sexlinks it's ridiculously easy:
Cross a male Ameraucana or other non-barred blue egg breed over barred females that lay white or brown eggs.

Wouldn't that only get me blue eggs? Additionally, how can I be sure of BB on the rooster when purchasing?

Blue egg male x white egg female = light blue eggs
Blue egg male x brown egg female = green eggs (shade will vary based on how dark the brown is)

You'll want NON-barred males, so simply don't buy one with any barring and you'll be in good shape.

Cream legbar lay medium blue eggs. Autosexing so you can tell boys from girls at birth

I was looking at them, but at 30 dollars a chick, that's pretty expensive

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

And if I crossed an olive egger with an amerauncana that would produce 50% green layers and 50% blue layers?

And assuming all of that is correct, how would I go about getting a barred olive egger?

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

Sorry to jump on this post out of nowhere but just curious as to why you don't want a barred male? Im new and have never bred chickens. And I have a EE that is obviously crossed with something because he is barred.

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.

I think I can answer this. Barred is a sex linked attribute. In chickens, the genetics of male and female are reversed. They aren't called X and Y, but essentially, males have XX and females have XY. So if the female has barred on her X gene, then genetically speaking, only and all of the males would be barred, because the female would only supply the X gene to a male.

If the male were barred, he could supply the barred X to either males or females and thus, would be of no use in sexing.

Am I correct?
