My current roo Thor only showed one consistent behavior as a young chick. He was very watchful. All the pics I have of my flock as chicks show Thor giving me "stink eye", paying very close attention to the strange creature and her camera.
He didn't engage in the chest bumping, play fighting as much as most of the chicks. He was just watchful at all times, even when the others were napping.
