ok, my chicks are about 2 1/2 weeks now and just today I've noticed that they'll kinda run at each other.. stand tall (stretch their necks as far as they can) and bump each other in the chest. Is this just establishing pecking order? they're not hurting each other and frankly remind me of a bunch of rambunctious teenage boys.... they're hysterical to watch... just wondering what it's all about? thanks
