I agree that the breed may have something to do with it. Our GLW like us well enough when we have treats, and are fine with being held or pet but don't seek it out. Our Easter Eggers, though, love to be held and will sit on our laps and follow us in the house if we'd let them. We have some new chicks - our Buff Orpington seems to fear us like we're going to pluck her feathers or something, the red sexlink is super friendly and the Polish is a complete spaz who likes to be cuddled if you can catch her. Go figure. All raised the same, together. I'd heard Buff Orps were friendly but ours doesn't seem to be for some reason. Kind of skittish compared to the others - not counting the Polish who is in a class of her own.
