I think different breeds lean toward friendliness, but each bird is an individual and doesn't always follow the trend. And I think friendliness can rub off, to an extent. I am raising some EO Basque, which are known for friendliness, with some other mixed chicks. This flock seems calmer, generally speaking, to others I have raised, and they all try to follow me out the door.
I am thinking it works the other way around as well. Not good for me. We will be selling them all if they don't calm down and become somewhat friendly. They freak out when we hold them and have already hurt my 3 year old. They are 3 weeks old today.
