    Using a French Black copper Marans Roo on other breeds (isa brown, RIR) to increase egg production but keep dark eggs? Is it possible?

    Dominant copper is a BCM roo and a Barred Rock Hen. They produce dark dark brown eggs like a 4-5 on the marans egg color chart.

    I have the Jenks dominant copper laying dark dark chocolate eggs, daily. It is a BCM and barred rock cross.
