How long has a chicken survived with its head cut off?

Chicken with No Head Keeps On Running

  • After a chicken has its head cut off, it can run around for up to a minute or longer, since the spinal nerves continue to send impulses to the muscles.
  • There is documentation of a chicken living 18 months after having his head cut off while being slaughtered. His name was "mike the headless chicken". In his case, the axe missed the stem of the brain which runs all the processes vital to life, allowing him to live.
