    I know what % you get if you cross a blue to a blue. And I know what you get from a splash and black (as long as the black carries the blue gene). But if I crossed two blacks would I still get 100% blues? And the same with splashes. And if I crossed a blue bird with a splash bird what would the % of blue splash and black be? Thanks in advance for the answers.

    You're almost on the right track except that a black bird does not carry a "blue" gene. If a black bird has a single blue gene it is then blue. If it has two blue genes it is then splash. Blue is created by a modifier that dilutes black to blue. The breakdown is listed below:

    Blue x Blue will give you 25% Black (without the blue gene) 50% Blue (with one blue gene) 25% splash (with two blue genes).

    Black x Blue will give you 50% Black and 50% Blue.

    Black x Splash will give you 100% Blue.

    Blue x Splash will give you 50% Blue and 50% Splash.

    Splash x Splash will give you 100% Splash

    Are those color genetics applicable to all breeds of chickens?

    Yes, they are just color genes, it applies to all breeds

    How does self-blue work?

    Guitartists,
    When you say self blue do you mean the Lavender gene?

    lav X black = all blacks carrying the lav gene

    black/lav X black/lav = 25% lavenders, 50% black/lav and 25% pure black - it is best not to keep any of these blacks because you don't know visually which is pure and which is a carrier but you can test mate them later if you need to grow them all for some reason

    lav X lav = 100% lavender HS

    Quote:So if I crossed a black to a black I would get 100% black? Thanks for clearing that up. Poultry genetics are confusing for me.
