I had two Orpingtons, named Oodle and Doodle.
Doodle was the best chicken I have known, and she passed away earlier this week. However, she laid one to two eggs a day for me, came when called, and I was always holding her in the yard. She could be pet any time and never fussed. Even when my daughter roughly patted her, poked her, or sloppily attempted to pick her up, Doodle just stayed still, never pecking, running, or kicking. Oodle, the surviving Orp in my little flock, is also quiet and friendly, though much shyer than Doodle had been. Oodle allows me to touch her at least once a day and comes when called as well, although she walks away when I move too fast or my daughter pulls her tail feathers. Still, no aggression what-so-ever, and she gives me an egg a day!
I would buy Orpingtons again, as a good family chicken breed.
