My buff orpingtons like to do "the chicken swing." I pick a hen up while bending low to the ground and gently swing her back and forth between my legs. It's sort of like a baby in a swing. My hens relax and go trance like. They also like the undersides of their wings gently stroked. A "wing pit" rub. What do your chickens like when they're getting special attention?
Mine love, love, love the comb and waddle massaging. They fall asleep to it. This is one of the very reasons I love chickens.
