In the daily quest "Chasing the Chicken" in Valley of the Four Winds, you run around picking up chickens until you find Old Hillpaw's Prize Chicken. The other chickens each have some action you need to perform with the "special" button that appears in the middle of the screen - take them to the chicken coop, put them in the water, etc. However, you can bypass this by just canceling the chicken buff on you. This takes away the chicken and allows you to pick up a new one. Just a tiny tip, but saves a bit of time since you don't have to carry the chickens around.
