Can a chicken really live without its head?

Poultry seem to be pretty low on the evolutionary chain, at
least so far as grey matters, but few more so than Mike, the
Headless Chicken of Fruita, Colorado. After having his head
lopped off  on September 10, 1945, Mike continued to run
around, attempt to preen his feathers, and even try to crow,
for a whopping eighteen months. Feeding him with an eye
dropper, promoter Hope Wade turned "Miracle Mike" into quite
the sideshow attraction for his remaining months (pulling
down no less than $4,500 per month). At his height of
popularity, Mike was even featured in Life magazine. He was
also examined by the officers of several humane societies
and declared to have been free from suffering. Regrettably,
in March of 1947, Mike succumbed to the inevitable and his
wild ride was over. But the legend of Miracle Mike lives on
to this day!
