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 mostly cut off.
Farmer Lloyd Olsen had his mother-in-law around for supper and was sent out to the yard by his wife to bring back a chicken. Olsen chose a cockerel named Mike and chopped his head off.
But Mike was still able to balance on a perch and walk clumsily; he even attempted to preen and crow! After the bird did not die, a surprised Mr. Olsen decided to continue to care permanently for Mike, feeding him a mixture of milk and water via an eyedropper. He was also fed small grains of corn.
In March 1947, Mike started choking in the middle of the night.
