My almost ten week olds (15 of them) are let out into the yard every evening about an hour or so before sundown (they go right back into the coop to put themselves to bed at sundown, it's really neat). When I first let them out, they all jump down onto the ground and do an initial peck around a bit, and then one will run and fly, that sets off four of five of them, and they all do the same thing. They jump in the air and fly at each other, land, and then do it again. Is this a pecking order thing? They settle down after awhile. It's a hoot to watch, some of them even bounce off my leg or arm in the process, they're so involved in whatever they're doing.
