yes there is a lady out where I live that has some. Really neat looking. hers look like pea combed blue copper Marans that are mostly laying dark dark olive eggsthis is correct. infact you can keep breeding your 3/4 birds back to marans to kill two birds with one stone(no Pun intended): first to make darker olive eggers and second to make them look more like marans in type and color. now after some time doing this back crossing you will have Pea combed marans that lay super dark olive eggs
