What I meant was, are all Maran roosters similar in temperament regardless of breed (birchen,black copper, cuckoo etc.) ? In other words, are black copper maran roosters meaner than cuckoos? Are birchen more easy-going than cuckoos? Or is plummage the only difference between them?[/quote]
My Golden Cuckoo and Black copper Roosters are well behaved. Non Aggressive to people. Neither overmates the hens and and always come running when a hen squawks. They are very vigilant toward threats as well.
