My vote would be for Brahmas. They are very friendly and beautiful chickens with feathers on there legs. They lay nice brown eggs and are considered a heritage breed.
I second this. I have about 15 different breeds in my flock and brahmas are by FAR and away my sweetest, behind the silkies which aren't recommended for egg supply..
I've seen EE mentioned a lot. I guess I just got unlucky with EEs. They've been skittish, unfriendly, sometimes downright aggressive.. Barred Rock...just pretty passive. Wyandottes...mine are curious and not skittish, but are kind of like puppies..try to be friendly but peck so hard out of curiosity it's drawn blood..lol. I also recommend Naked Necks for personality, but the looks aren't for everyone..hehe.
