Hi guys! I have solid blue marans no copper mixing in them! Their darkest egg is a. 5- 6 and lowest a 3 how do i improve them without using copper? Thanks
Chances are, what you have is a bird that does carry the copper gene, she is just not expressing (showing) it. I have two of them here, neither showing copper, but I know they have copper in their background. You will really have to hunt high and low to find solid Blacks or Blues. If they tell you they came out of a Blue Copper or a Black Copper several generations ago, they will still carry the copper gene!
