Way too much miss information out there on Black Copper Marans. Black Copper Marans were admitted into American Standard Of Perfection just 2 years ago, It may have been 3 years. They used mostly French standards and they must have feathered legs. Not hard to fix but should have feathered legs. English Standard calls for clean legs. They just wanted to be different.
There is a web site International Black Copper Marans Forum 1500 pages of proper Marans breeding go there read it. The true number 1 quality of Marans is egg color. Very hard to find and breed . I am in Eastern Wash. state. Have been Black Copper Marans for 5 years and I love these birds. You will not get quality birds from the hatchery and you will not get the dark eggs. TOM
