Cucco Revenge Squad

You throw a chicken egg at a point you can see within range. Each creature in a 20-foot-radius centered on that point makes a Dexterity saving throw, taking 8d6 force damage on a failed save or half as much damage on a successful one, as a swarm of Chickens spawn from the ether, pecking the target in a frenzied swarm. 

The chickens attacks count as magical for the sake of overcoming resistance.

Using a Higher-Level Spell Slot. The damage increases by 1d6 for each spell slot level above 3.
