Chicken

Chicken is a common large Bonus Bird with 16 HP that wanders the battlefield, moving to random tiles each turn before fleeing on its third turn. Killing it grants +1 All Stats Up and a bonus item — possible drops include Rotisserie Chicken (15 HP heal), Golden Egg (extra coins per battle), Weird Egg (chance to spawn a fetus familiar), or Raptor Egg (full heal with spawn chance). Worth pursuing before it escapes.
