Thanks, big medicine. I always know what I'm trying to say, but you always seem to say it so much better!Just to follow up on bumpercarr's answer here.
As stated, one copy of blue gets you blue, two copies splash, but no copies gets you black. As the blue gene only affects the black part of a feathers pattern, the feathers base color gold or silver is not altered. So no copies of blue gets you a black penciled feather in partridge pattern be it gold, red (mahogany in true partridge) buff, or even silver in darks.
Blue to blue breedings result in 50% blue, 25% splash, and 25% black chicks + or -.
blue to black, 50% blue, 50% black.
Right idea, just cleaning up the terminology some.
