Swing the chicken the same direction the prop swings (CCW from your point of view) 2-3lb chicken w/ feathers (no fair using a frozen chicken - That's why we can't break in an engine here in Minnesota in the winter. By the time you're through, You, the Chicken AND the engine are frozen!)

In Australia, you can use an Emu or a Kiwi, but not an Ostrich! A Wallaby will work too, if you can lift one.
