Chicken Chaser

When you drink this potion, your hair turns dark red (if you have any), and you gain the ability to speak with chickens permanently, as if by the Speak with Animals spell. Additionally, you can crow a sacred and thunderous cackle that summons 100 chickens in a 20-foot radius centered on you. These chickens appear running from a distance, digging out from the ground below, and falling from the sky in a veritable tsunami of flapping, clucking poultry. Each creature in the area (excluding you) must make a DC 19 Dexterity saving throw, taking 30d6 slashing damage on a failed save, or half as much damage on a successful one. Once you've summoned the chickens in this way, you can't do so again. This doesn't count against the number of potions you can have affecting your body at once.
