Mike the Headless Chicken

Mike the Headless Chicken (April 1945 – March 1947), also known as Miracle Mike, was a Wyandotte chicken that lived for 18 months after his head had been cut off. Although the story was thought by many to be a hoax, the bird's owner took him to the University of Utah in Salt Lake City to establish the facts.

Beheading

On September 10, 1945, farmer Lloyd Olsen of Fruita, Colorado, United States, was planning to eat supper with his mother-in-law and was sent out to the yard by his wife to bring back a chicken. Olsen chose a five-and-a-half-month-old cockerel named Mike. The axe missed the jugular vein, leaving one ear and most of the brain stem intact.

Despite Olsen's failed attempt to behead Mike, Mike was still able to balance on a perch and walk clumsily. He attempted to preen, peck for food, and crow, though with limited success; his "crowing" consisted of a gurgling sound made in his throat.

When Mike did not die, Mr. Olsen decided to continue to care permanently for the bird. He fed it a mixture of milk and water via an eyedropper, and gave it small grains of corn.

Fame

Once his fame had been established, Mike began a career of touring sideshows in the company of such other creatures as a two-headed calf. He was also photographed for dozens of magazines and papers, featuring in Time and Life magazines.

Mike was on display to the public for an admission cost of twenty five cents. At the height of his popularity, the chicken earned US$4,500 per month ($47,500 today) and was valued at $10,000.

Death

In March 1947, at a motel in Phoenix on a stopover while traveling back from tour, Mike started choking in the middle of the night. The Olsens had inadvertently left their feeding and cleaning syringes at the sideshow the day before, and so were unable to save Mike. Olsen claimed that he had sold the bird off, resulting in stories of Mike still touring the country as late as 1949. Other sources say that the chicken's severed trachea could not properly take in enough air to be able to breathe, and it therefore choked to death in the motel.

Post Mortem

It was determined that the axe had missed the jugular vein and a clot had prevented Mike from bleeding to death. Although most of his head was severed, most of his brain stem and one ear were left on his body. Since basic functions (breathing, heart rate, etc.) as well as most of a chicken's reflex actions are controlled by the brain stem, Mike was able to remain quite healthy. This is a good example of central motor generators enabling basic homeostatic functions to be carried out in the absence of the cerebral cortex.
