A Blue copper is not genetically a pure variety .it is a semi washed up Black . it is just a plumage shade .
to get a correct shade of blue .a person has to breed them new each time from a Black copper rooster over a Blue copper hen . F1 progeny.
never ,never ,never use a Blue copper rooster over a Blue copper hens .very bad practice .
Marans people how make the SOP do many mistake . they don t accept a Splash { Breed true} as variety but they want to force a blue instead . the Genetic does not listen to people . it is a low of nature ,has to be respected .
chooks man
would blue copper roo mated to a black copper hen give good results too?
