On a Tuesday evening in September 1945, Lloyd Olsen went out to his backyard in Fruita, Colorado, with one goal: kill a chicken for dinner. His mother-in-law was coming over, and she apparently had a thing for the neck meat. Lloyd, being a dutiful son-in-law, aimed his axe to save as much of that neck as possible. He swung. The head came off.
But Mike the Headless Chicken didn’t die.
He didn't even fall over. After a brief, chaotic flutter—the kind you’d expect from any bird meeting its end—Mike just stood up. He shook his feathers. He tried to peck at the ground for food, despite having no beak. Honestly, he just went back to being a chicken. Lloyd, understandably weirded out, left the bird in an apple box on the porch. When he woke up the next morning and found Mike sleeping with his non-existent head tucked under a wing, he knew his dinner plans had turned into something else entirely.
How Mike the Headless Chicken Actually Survived
It sounds like a tall tale from some dusty 1940s tabloid, but it was real. Scientific American and the University of Utah eventually confirmed the "miracle."
Basically, Lloyd’s aim was so specific that he missed the jugular vein. A blood clot formed almost instantly, which stopped Mike from bleeding out. But the real kicker is the brain. See, a chicken’s brain is tiny and shoved into the back of its skull at a 45-degree angle. By aiming high and leaving the neck intact, Lloyd accidentally left about 80% of Mike's brain—including the brain stem—completely untouched.

The brain stem is the "autopilot" of the body. It handles the stuff you don't think about. Breathing. Heart rate. Reflexes. Because that part was still there, Mike could still walk, balance on a perch, and even attempt to preen himself. He lived for 18 months. A year and a half of being a global celebrity without a face.
You’ve gotta wonder what was going through Mike’s remaining brain cells. He would still try to crow in the mornings, though it came out as a "gurgling sound" from his throat.
Life on the Road as a "Headless Wonder"
Lloyd realized pretty quickly that a headless bird was worth more than a chicken dinner. He started touring. Mike was featured in Time and Life magazines. People paid 25 cents to see him, which was decent money back then. At the peak of his fame, Mike was raking in about $4,500 a month. In today’s money, that’s over $60,000.
The logistics were... messy. Lloyd fed him using an eyedropper, dripping a mix of milk and water directly into his esophagus. He’d also drop in small grains of corn. The biggest challenge was the mucus. Without a head to clear his own throat, Mike would often start to choke. Lloyd had to use a syringe to manually clear out Mike’s airway several times a day to keep him from suffocating.

The Tragic Motel Room Incident
The story of Mike the Headless Chicken ended in a way that feels almost preventable. It was March 1947. The Olsens were on their way back from a tour and stopped at a motel in Phoenix, Arizona. In the middle of the night, Lloyd heard Mike gagging.
He reached for the syringe. It wasn't there.
They had accidentally left it at the sideshow the day before. Without the tool to clear his throat, Mike choked to death right there in the motel room. For years, Lloyd told people he’d sold the bird off, probably because he didn't want to admit he’d let his meal ticket die over a forgotten piece of equipment. It wasn't until later that the truth came out.
Why We Are Still Talking About This Bird
Fruita, Colorado, hasn't forgotten him. Every May, they hold the Mike the Headless Chicken Festival. There’s a 5k run, a wing-eating contest (which is a bit dark, if you think about it), and a statue.

But beyond the "freak show" aspect, Mike actually taught scientists a lot about how much the brain stem handles. He proved that the "higher" functions of the brain—personality, sight, complex thought—aren't strictly necessary for the body to keep the lights on. Mike was, for all intents and purposes, a living reflex.
Key Lessons from Mike’s 18-Month Survival
If you're looking for the "why" behind this bizarre piece of history, it usually boils down to three specific things:
- Precision (or lack thereof): The axe stroke was high enough to leave the ear and the base of the brain.
- The Blood Clot: Without that lucky clot, Mike would have bled out in minutes.
- Human Intervention: Mike wouldn't have lasted two days without Lloyd’s constant feeding and throat-clearing.
If you're ever in Fruita, you can see the metal sculpture dedicated to him. It’s a weird reminder that sometimes, nature (and a botched butchering job) can produce something that defies every rule we think we know.
