One of the best birchen Marans breeders here in the states is Harvey Moore. He's got much greater pool than myself, and he's got a Facebook group called birchen Marans. Mine aren't from him directly, but if I need more later, that's where I will go. He also is working on a blue birchen project, but on a scale I can't match.Bantambird, I just love your birchens. I would love to have one someday. I think birchen may be my most favorite marans color!!
