Mike the Headless Chicken
In 1945, a chicken named Mike became known as "The Headless Wonder Chicken" after surviving despite having his head chopped off. Although most of his head was severed, including his eyes and mouth, Mike lived for 18 months after the beheading, becoming a national sensation and touring sideshows.
Mike's story began in Fruita, Colorado, when farmer Lloyd Olsen was sent by his wife to bring a chicken for supper. Olsen chose a five-and-a-half-month-old Wyandotte chicken named Mike. When Olsen attempted to behead Mike, the axe removed most of the head but missed the jugular vein, leaving one ear and most of the brain stem intact. This section of the brain controls basic functions such as breathing and heart rate, allowing Mike to survive.
After the beheading, Mike ran around like any other headless chicken, but he didn't stop running and survived. Olsen decided to care for the bird, feeding him a mixture of milk and water through an eyedropper and giving him small grains of corn and worms. Word spread, and soon Mike became famous. He was taken on the road as a sideshow attraction, earning his owner the equivalent of $60,000 per year in today's money. People paid to see him, and he was featured in magazines and newspapers, even appearing in Time and Life magazines.
However, Mike's fame was short-lived. In March 1947, while staying in a motel during a tour, Mike choked on his mucus in the middle of the night. Olsen had inadvertently left the feeding and cleaning syringes elsewhere, so he was unable to save Mike. Despite his tragic end, Mike's legacy lives on in Fruita, Colorado, where an annual "Mike the Headless Chicken Day" is held, featuring events such as the "5K Run Like a Headless Chicken Race", egg toss, and "Chicken Bingo". Mike's story also inspired a poultry-themed comedy punk band, The Radioactive Chicken Heads, who wrote a song titled "Headless Mike".

How did Mike survive?
Mike the Headless Chicken survived because, despite losing his head, most of his brain stem remained intact, and a clot prevented him from bleeding to death. The brain stem controls a chicken's basic functions, including breathing and heart rate, as well as most of its reflex actions. This allowed Mike to remain quite healthy and even travel around the country as a sideshow attraction.
Mike's survival can be attributed to a combination of factors, including the angle of his brain within his skull and the precise location of the axe cut. Dr. Wayne J. Kuenzel, a poultry physiologist and neurobiologist, explains that the skull of a chicken has large eye openings, allowing the brain to sit at an angle. As a result, even when part of the brain is severed, the critical functional areas for survival can remain intact.
In Mike's case, the axe removed his beak, face, eyes, and an ear, but it is estimated that up to 80% of his brain mass remained, including the essential areas for controlling his body's functions. This is in contrast to humans, where losing one's head would result in the loss of almost the entire brain.
After Mike's beheading, his owner, farmer Lloyd Olsen, decided to care for the bird. Olsen fed Mike a mixture of milk and water using an eyedropper and also gave him small grains of corn and worms. Mike lived for 18 months after losing his head, achieving national fame during this time.
Mike's survival was an anomaly and a wonder of biology that fascinated people across the country. He toured sideshows and was featured in magazines and newspapers, even appearing in Time and Life magazines. At the height of his popularity, Mike's owner earned significant income from his fame, and Mike himself was valued at $10,000 (equivalent to $140,800 in 2024).

Mike's fame and career
Mike the Headless Chicken, also known as Miracle Mike, was a male Wyandotte chicken that lived for 18 months after being beheaded. Mike's fame was established after he survived the beheading, which left his brain stem and one ear intact. This anomaly sparked national fascination, and Mike became a celebrity, touring sideshows and being featured in magazines and newspapers, including Time and Life.
Mike's owner, farmer Lloyd Olsen of Fruita, Colorado, played a significant role in the chicken's newfound fame and career. In 1945, Olsen attempted to behead Mike to serve him for supper. However, despite losing most of his head, including his beak, face, eyes, and an ear, Mike remained alive due to a blood clot that prevented him from bleeding to death. Recognizing the uniqueness of the situation, Olsen decided to care for Mike, feeding him a mixture of milk and water through an eyedropper.
As news of the headless chicken spread, a sideshow promoter named Hope Wade approached Olsen with a proposition to take Mike on tour. Together with his wife, Clara, Olsen accepted the offer, and the trio embarked on a journey across the United States, exhibiting Mike as a wonder of biology. Mike's ability to stand, walk, perch, and even attempt to preen and peck for food fascinated people, and he soon became a national sensation.
At the height of his popularity, Mike's owner earned substantial sums, with Mike himself valued at $10,000 in 2024 values. The public paid admission fees to catch a glimpse of the extraordinary bird, and his story was widely publicized in the media. Mike's fame and career as a sideshow attraction were short-lived, however, as he met an untimely end in March 1947 while touring in Phoenix, Arizona. Mike choked on his mucus and, without the necessary feeding and cleaning syringes, Olsen was unable to save him.
Despite his demise, Mike's legacy endured, with an annual "Mike the Headless Chicken Day" held in Fruita, Colorado, and a festival celebrating his memory. Mike's story remains a testament to the resilience of life and the unpredictability of fame.

Chicken anatomy
A chicken with no head is called a "headless chicken", and one famous example is Mike the Headless Chicken. Now, let's focus on chicken anatomy.
Beak and Tongue
The beak is a crucial part of a chicken's anatomy, as it is the primary means by which they can move or pick up objects, including food. Inside the beak is a triangular tongue that has several functions, including tasting food, latching onto treats, and aiding in making various noises.
Crop and Gizzard
The crop is a muscular bag at the base of the chicken's neck that stores whatever the chicken puts in its mouth. It should be empty in the mornings and gradually fills up throughout the day, taking the shape of a small ball. The contents then pass into the gizzard overnight and empty out. The gizzard is a muscular organ that grinds and mixes food, as chickens do not have teeth and swallow their food whole.
Digestive System and Diet
Chickens are omnivores, consuming both plants and animals. In the wild, they scratch the soil to find seeds and insects, and they also eat larger creatures like lizards and young mice. They do not possess a rumen, so they cannot digest the cellulose of forage.
Reproductive System
Understanding the female reproductive system is vital for addressing issues related to egg production, fertility, and hatchability. The oviduct, a 25-27 inch tube along the backbone connecting the ovary and tail, is a key component. The egg yolk forms in the ovary, and during ovulation, the yolk enters the oviduct, which is divided into five sections: infundibulum, magnum, isthmus, shell gland, and vagina.
Muscular System
Like all animals, chickens have three types of muscles: smooth, cardiac, and skeletal. Skeletal muscles are responsible for the chicken's shape and voluntary movements, and they are the type of muscle consumed as poultry meat. Tenders, also known as chicken fingers or strips, are obtained from the pectoralis minor muscles on either side of the breastbone.

The ethics of beheading chickens
Beheading chickens is a practice that has been carried out for various reasons, including food preparation, dispute resolution, and even as a sideshow attraction. While the act of beheading a chicken may be necessary for some, it is important to consider the ethical implications and the potential impact on animal welfare.
The Impact on Animal Welfare
The welfare of chickens is a significant concern when discussing the ethics of beheading. While some may argue that chopping off the head is the most effective way to end a chicken's life, it is important to acknowledge that the brain remains conscious for several moments after decapitation. This means that the chicken may experience suffering during this time, which is ethically questionable.
Humane Alternatives
Those opposed to beheading chickens may suggest alternative methods of euthanasia that are considered more humane. Some suggestions include the use of a high-powered pellet gun to instantly kill the brain or separating the heart and brain as swiftly as possible. However, these methods also come with their own set of challenges and risks of causing unintended suffering.
Cultural and Traditional Practices
In some cultures, chicken-beheading rituals hold significant importance and are embedded in traditional practices. For example, Taiwanese chicken-beheading rituals are used as a form of dispute resolution, where individuals proclaim oaths of innocence before their deity. While these rituals may have played a crucial role in the past, the rate of their practice has declined with modernization.
Life After Beheading
It is worth noting that in rare cases, chickens have been known to survive for extended periods after being beheaded. One notable example is Mike the Headless Chicken, who lived for 18 months after his head was partially chopped off, leaving most of his brain stem intact. While Mike's case is unusual, it raises questions about the assumptions of instantaneous death following decapitation.
Public Display and Entertainment
In conclusion, the ethics of beheading chickens encompass a range of considerations, including animal welfare, cultural traditions, and the potential for prolonged life and public display. While there may be varying opinions on the justifiability of beheading chickens, it is essential to approach the practice with empathy and a commitment to minimizing any potential suffering.
