Thanks, for the info. I am interested in the Black Copper Marans, still at the research stage. I keep seeing some advertised as black and blue. Soon, I will be trying to find good breeder(s) to get stock from.
If you want to work only with the BCM they sound NOT be from a Blue mating. You can and should use blacks in the blues but not vise versa. I use blacks in my blues because I don't like to breed for splash. I will breed blue to blue but always have blacks in the pen too.
