Are you wanting to get rid nof him or looking for mates? I dont have a blue, but i have a CooCoo Marans, a Birchen Marans and French Black Copper Marans all four months old, not in service yet, but no blues. They alll have feathered legs from their papay which is a French Black Copper Marans, I plan to keep the Black and Birchen for back up to my FBCM breeder.I have an olive egger cockerel that is blue. He is Marans x Isbar.
I know someone that posts here now and then breeds Marans, just can't remember who. Maybe they will pop in.
