Blue x Blue = 50% blue, 25% black, 25% splash
Blue x Black = 50% blue, 50% black
Blue x Splash = 50% blue, 50% splash
Black x Splash= 100% blue
Now, when breeding blues, you will get some that appear black but will breed like a blue. I assume they are simply very dark blue. I made a mating this last year of a brassy back cock over a blue brassy splash hen, which should have resulted in all blues, yet i got some sports. That should not have happened, genetically, until I found out the brassy cock came from blue brassy breeders.
