I haven't decided yet whether to keep them because I'm also working on another Olive Egger project. They would mostly breed true because their phenotype, the Blue Copper, is dominant - with the exception of the fact that the blue does not breed true (keeping in mind the B/B/S rules). One or both is probably also carrying the recessive Wheaten from the mother. So, while they would not breed true 100%, the outcomes should be pretty predictable.
