As Sinthoniel said, it is probably player-caused. What probably happened is chickens spawned everywhere, like they always do because chickens are dumb, and then people walked around and picked up eggs, and then threw them. There then were more chickens, and therefore more eggs, and therefore more chickens. I suggest you start hunting them.
