Any chicken in the pot is friendly to me. :) Any chicken unfriendly goes in the pot.
{I raise mutts, honestly can't speak to aggressive breed tendencies. All my "root stock" birds were chose either because they were productive, or because they werer predator aware [usually means "flighty"]...
I.... haven't a clue.
Honestly, not much of a breed fan, and friendliness is not a trait I'm selecting for in my culling project. Not seeking aggression either. "Predator Awareness" is the behavioural trait I most value.
