Evil Chicken

The Evil chicken is a random event which can occur at any time, during any action, even while standing around or in combat. It is the only hostile random that is not skill related.

It attacks with magic, and so cannot be hidden from, and may inflict a hit or two as the player runs away.

The Wise Old Man of Draynor Village has a book on the origin of the evil chicken, titled simply "Book on chickens".
