If interested -
BBS is short for Blue, Black, Splash.
Blue is a dilution of black (1 copy blue dilution)
Splash is 2 copies of blue dilution, one from each parent
Crossing the colors together, you can get any of the colors
(this part doesn't matter which is rooster and which is hen)
Black x Blue = % black offspring, % blue offspring
Black x Splash = all blue offspring
Blue x Blue = %blue, %black, %splash
Blue x Splash = % blue, % splash
Splash x Splash = all splash offspring (I've heard splash can get lighter in this pairing)
