I don't think there are any guarantees. I had a super sweet Delaware hen, so I bought two more the next year and they weren't that friendly. This year a couple of my Black Australorps and a Barred Rock have been most likely to jump up on my lap for some attention. My Wyandottes have been really friendly, too, including the rooster. They will run to greet me, but they don't like to be petted that much. I also have a white crested Polish that follows me around and a white leghorn (of all things) that rubs against me like a cat. My Easter Eggers are most stand-offish. I was just commenting tonight that I don't think they love me much. Maybe that's why they are also the only breed not yet laying.
