No head? No problem!
It'll take a lot more than headlessness to keep the chickens from participating in this thing, whatever it is. Hey, as long as the event is dedicated to the proposition that chickens are nothing but objects, they'll be there, dead, headless, and fried.
These are hardy birds and they're used to putting up with the worst the animal-eating industry can dish out.
So step out of their way and see how a real athlete gets the job done!
