I was always told not to mix a black copper with the wheaton that's why but robbers in wheaton forever so messed up to this day some people can't tell the difference between a black copper rooster and a wheaten marans rooster . this is ciniminn wing triangle is a good indication that its wheaten. a bcm + wh cross is fine if your just haveing fun .but i wouldnt recomend . I've never done it but I think the hens wpuld be the most messed up
