Let's go back to September 10th, 1945 in the very small rural town of Fruita, Colorado. Lloyd Olsen's wife, Clara, sends him out to kill a chicken for dinner. Lloyd fells the axe on the chicken's neck. The head comes off and the chicken, oblivious to the loss of his head, keeps right on going about his bird business. When Lloyd found him alive and well, sans head, the next morning, he decided to let the bird live and fed him with an eye dropper to keep him going.
They named him Mike and Mike became so famous that for the remaining 18 months of his headless life, he hit celebrity status; he even wound up in both Time and Life Magazine.
That celebrity status became legend and now there is an annual Mike the Headless Chicken festival in Fruita, during the third weekend of May. The festival features a lawn mower race, chicken dance contest, eating contests, chicken games (like pin the head on the chicken and an egg toss), 5k run, a car show and a 'Good Egg' award, among several other interests.
