Also, I wanted to share my experience with doms vs their flock mates. Doms are definitely the leaders no matter what else I have in there with them, except my American games which I keep away from everyone else. The doms will chest butt anyone doesn't matter if its young pullet against a full grown rooster of larger breed. However they are not mean or pecky, very fair. The older hens are much more reasonable than the pullets.
With this said, it is important to choose flock mates that are not overly shy - Ameraucana and olive egger was a poor choice and we got rid of them, they just couldn't hold their own with the doms. I would NOT put silkies in with them, or probably even orpingtons unless you have lots of space or free range them. Australorps prob ok, also Marans which were a good match. I keep mine with Buckeyes now and it is a very good match.
My doms are not overly tame (except those I got from another breeder), they do allow me to pet them when they're on their roost at bedtime, but if I have to pick one up, the males are no problem but the girls say "talk to the wing!" and dash away. I raised them all and handled as chicks daily but they grew out of their tameness at puberty. I guess they are used to getting away from the boys!!
ETA - about boys, I just trimmed my flock down to only 3 roosters, all doms now and I have to say I cant be more pleased with the dom roosters, they do not fight, the orig cock is so even tempered he is happy to share his favorite wives with his sons and if he does have a problem with anything, he just walks up and the son runs off, no fighting. They are level headed around the kids too.
