Okay, so pure birchen roo, completely silver hackle, no blonde or straw in his hackle, he would be pure silver birchen.
Your black hen, if she is first generation from BC and cuckoo, she will carry birchen genes, and gold if the BC was the rooster. If they were crossed back to the cuckoo several times, then she could be pure black, if the cuckoos are true extended black based cuckoos. I've seen pictures of cuckoos that look like barred silver birchens.
So she is pure black, and he is pure birchen, then you will get pure black, or some black and some blue if the birchen roo is blue birchen.
Birchen and gold genes hide under extended black. It's hard to know the purity of a solid black until you breed it.
ETA I think that the Blue roo does not have birchen feathers in his hackle, it's just the gloss of the shinier hackle feathers. He looks like a blue version of the first black roo to me.
ETA: I guess I should clarify terms. Do you mean pure blue as in no other coloring in the feathers, or genetically pure?
Lots of different mixed breedings can produce a visually pure blue Marans, especially hens. Getting them genetically pure is the hard part. Your Birchen roo will never produce genetically pure blue offspring. Breeding his offspring back to the hen would, if she is indeed pure black.
I thought maybe the roo in the photo had some birchen, because she stated in that post they he was from black coppers.
Anyway, yes the hen in question, is I think F4 bred back to the cuckoo. In the hatch, I got a single barred cuckoo male, 2 black hens, 1 black roo, and a couple of black copper roos. Unfortunately, I only have the 1 hen left. So, trying to figure out what to do with her...
