Can't help you on breeds, but to help tame them spend a lot of time just sitting with them, in their coop and run, and after you see they have calmed down some offer them treats (mealworms work great!) from your hand. Toss some out towards them, letting them see its coming from your hand. Your bravest ones will eventually eat out of your hand, the most skittish ones will take a little longer to get comfortable with that. It takes time but if you are persistent you will get them tamed.
