Chicken Stampede

You fill forth a bunch of chickens (use weasel statistic)from another realm which panic and charge in a direction of your choosing. Any creature in the way must make a dexterity saving throw or take 7d6 piercing damage or half as much on a successful one. The chickens have a move speed of 30 ft and will run up to 60 feet before disappearing in a puff of feathers.
