In 1945, a chicken named Mike lived for 18 months without a head. After Lloyd Olsen beheaded Mike on his farm in Fruita, Colorado, the chicken got up and started running around. Olsen discovered that Mike was still alive the next morning and decided to care for him. Mike survived because most of a chicken's brain is located in the back of its head, and the axe missed the jugular vein. This allowed Mike's brain stem, which controls basic functions like breathing and heart rate, to remain intact. Mike's survival fascinated the public, and he became a famous sideshow attraction, earning significant revenue for Olsen. Mike's story inspired annual celebrations in Fruita, Colorado, and influenced popular culture, including music and architecture.

Mike the Headless Chicken lived for 18 months
On September 10, 1945, a chicken named Mike lived through a beheading and went on to survive for 18 months. Lloyd Olsen, a farmer in Fruita, Colorado, was preparing a chicken for dinner when he accidentally lopped off the bird's head with an axe. However, the chicken, later nicknamed "'Miracle' Mike", didn't die.
Olsen's axe had missed the jugular vein, and a clot prevented Mike from bleeding to death. While most of his head was severed, one ear and most of his brain stem remained intact, allowing him to continue living. The brain stem controls basic functions like breathing, heart rate, and reflex actions.
Mike's fame spread, and he became a sideshow attraction, touring the country and appearing in magazines and newspapers. At the height of his popularity, Mike's owner earned $4,500 per month (equivalent to $63,400 in 2024). Mike was valued at $10,000 (equivalent to $140,800 in 2024).
Mike's survival was an anomaly, but not an impossibility. While it is rare, chickens can sometimes survive beheading if the brain stem remains intact, allowing them to retain basic motor functions and the ability to breathe.
Unfortunately, Mike's luck eventually ran out. In March 1947, while staying at a motel in Phoenix, Arizona, he choked to death, ending his improbable 18-month survival story.

Mike survived because most of a chicken's brain is in the back of its head
In 1945, a chicken survived for 18 months without its head. Named Mike, the bird became famous and even toured sideshows. So, how did Mike survive for so long without his head?
It turns out that most of a chicken's brain is located in the back of its head, behind the eyes. When Lloyd Olsen brought down his axe on Mike's head, he inadvertently lobbed off most of the chicken's skull but left the part of the brain that controlled vital bodily functions. This included the brain stem, which controls breathing, heart rate, and most reflex actions.
Reports indicate that Mike's beak, face, eyes, and an ear were removed with the blow. However, up to 80% of his brain by mass remained untouched, including the areas that control heart rate, breathing, hunger, and digestion. A timely blood clot also prevented him from bleeding to death.
After realizing that Mike was still alive, Olsen spent the next 18 months exhibiting the headless rooster at fairs, carnivals, and other public events. Mike's owner fed him by dripping water and liquid food into his oesophagus with an eyedropper and removed mucus from his throat with a syringe.

Mike's owner fed him a mixture of milk and water via an eyedropper
On September 10, 1945, Lloyd Olsen was beheading chickens on his farm in Fruita, Colorado. One chicken, however, did not die. This chicken, later named Mike, survived for 18 months without a head.
Mike's owner, Olsen, fed him a mixture of milk and water via an eyedropper. He also gave Mike small grains of corn and worms. This was possible because, despite losing most of his head, Mike's jugular vein was missed by the axe, and a clot prevented him from bleeding to death. Additionally, most of his brain stem and one ear remained, allowing him to control basic functions like breathing and heart rate.
Olsen soon realized that Mike was a money-making attraction. He began exhibiting the bird at fairs, carnivals, and sideshows, charging admission fees. Mike's fame grew, and he was even featured in Time and Life magazines. At the height of his popularity, Mike's owner earned the equivalent of $63,400 per month in today's money, and Mike himself was valued at $140,800.
Mike's story is a testament to the resilience of chickens and the potential for basic functions to be maintained even when higher brain centers are absent. Mike's survival inspired others to attempt similar feats, but none were successful, highlighting the rarity of his case. Today, Mike is remembered through events like Fruita's annual "Mike the Headless Chicken Day," which features a range of lighthearted activities.

Mike's owner earned $4,500 per month at the height of Mike's popularity
In September 1945, Lloyd Olsen was beheading chickens on his farm in Fruita, Colorado, when one of the chickens, Mike, survived the hatchet blow and continued to live without a head. Mike lived for 18 months after losing his head, during which he became famous.
Mike's owner, Lloyd Olsen, capitalized on his chicken's unusual condition and took him on tour. At the height of his popularity, Olsen earned $4,500 per month (equivalent to $63,400 in 2024). Mike was valued at $10,000 (equivalent to $140,800 in 2024).
Olsen fed Mike a mixture of milk and water via an eyedropper and gave him small grains of corn and worms. He also exhibited Mike at fairs, carnivals, and other public events, charging admission fees of 25 cents (equivalent to $4 in 2024).
Mike's survival can be attributed to the fact that the axe missed his jugular vein and a clot prevented him from bleeding to death. Additionally, most of a chicken's brain is located in the back of its head, and Mike retained enough of his brain stem to control basic functions like breathing, heart rate, and reflex actions.
Mike's fame inspired an annual "Mike the Headless Chicken Day" in Fruita, Colorado, featuring various themed events and activities. He also inspired a poultry-themed comedy punk band called The Radioactive Chicken Heads, who featured a Headless Mike puppet in their live shows and music video for their 2008 song "Headless Mike".

One of the chickens, Mike, survived the beheading and began walking around. Lloyd and Clara Olsen then spent the next 18 months exhibiting Mike at fairs, carnivals, and other public events.

Additionally, most of his brain stem, which controls basic functions such as breathing and heart rate, had remained intact.
Mike's fame led to a career in the sideshow circuit, where he was put on display for people to see. At the height of his popularity, Mike's owner earned a significant income, and Mike himself was valued at $10,000. However, on March 17, 1947, while on tour in Phoenix, Arizona, Mike started choking on his mucus and died. Lloyd and Clara Olsen, who were with him, realized that they had accidentally left the syringe they used to remove mucus from Mike's throat back at the sideshow.

The impact of Mike's story extends beyond just entertainment and into scientific understanding as well. The study of Mike's survival has provided valuable insights into chicken anatomy and the functions of their brains. According to Dr. Wayne J. Kuenzel, a poultry physiologist and neurobiologist, the skeletal anatomy of chickens plays a role in their ability to survive without a head. Additionally, Mike's case has sparked discussions about the ethical treatment of chickens in factory farms, with proposals to systematically rear brain-dead broilers to maximize production and curb chicken suffering.
