So I have 6 bantams and 6 regular sized chickens. They always break off into those groups the band comes with the bantams the regs with the regs. But what I've come to notice is that the regs don't leave them alone. They are constantly chasing them around and pushing them away from the food and water. They've only been integrated for a few weeks, does this Behavior go away or is this pretty regular for chickens to do to bantams?
