One of my RIR's is friendlier than the other, same for Australorps and Buff Opringtons. As far as breeds the Australorps are the friendliest. My Barred Rock and Wyandottes were a 9 days old when I got them and have been harder to train them to me. But I spend twice a day bringing each one out alone onto a towel and spend time touching, talking, holding, hand feeding them. I also go into the room where I house them at least 8 times a day and talk with them as a group, calling their names. I still have a couple that I ave to corner in order to retrieve but almost all of my 10 will sit on my hand or arm and when I try to push them off onto the towel they gently fight with me to stay on my arm.
