Is it normal for my chickens to scrap their beaks on things? It is a side to side motion. Also, is it normal for them to fluff their feathers up a lot:? I started getting nervous of mites but I haven't found any on them. Is it normal for them to run really fast across the run for no apparent reason? Can a pullet be aggressive just like a Rooster even when there is a rooster already in the flock? Any other behaviors I need to know about that are weird?
