I agree, breeders will cull aggressive birds. My Buckeyes tend to be very gentle. If you choose a large, dual purpose breed, they will be nicer. (Except for certain strains.) Breeders don’t tolerate aggression in the larger birds.
I love my buckeyes and they came from breeders but had one rooster very aggressive....was the sweetest cockerel till he turned a year old then he changed.....no guarantee on roosters from either really. Just a better chance if you buy from a breeder who breeds for calm temperament....still no guarantee.
