Morbius18 your cockerel has a stunning copper nice feathered shank nice wide shoulder .
Need more photos of him some close up shot.He s promising NOT a cockerel for a pot for sure.
I see you have a black copper pullets with a nice coppery hackel as she his sister. if yes you got your hand on a nice Black copper line. very hard to achieve .the balance between the copper and the black. and to keep the copper fron getting too dark.
