That mix should produce some very pretty eggs when the hens start laying!! I plan to breed my BCM roo with my OE and EE, and see the pretty egg colors I can get from those hens!
I have BCM's and OE's and EE's.........All of your black ones are the marans. The grey are your olive eggers, and the white one looks like my easter eggers but I suppose could be an OE.
