That sounds awesome. May you fill me in, good sir?
So basically someone activated some portal stones, and the portal stones attracted a bunch of chickens to the region in question. The swarm of chickens crowded around the portal stones until they activated, and then when the portal stones deactivated, the chickens charged out of the forest for a bunch of people to catch and eat. They were said to be the most delicious chicken anyone had ever eaten, but all who ate them gained random eccentricities until their dying day.
