Mike , The chicken without head

This chicken called Mike lived 18 months after his head had been cut with an ax.
In September 1945 a farmer in Colorado would decapitate Mike, who was then five months and a half to kill before eating but deflected the ax leaving intact the jugular vein, an ear and the brainstem.
Chicken, in addition to just survive, has managed to perch on a branch and trying to peck his neck with it although it is impossible.
The last surprise his owner began to feed him pouring milk and water with a pipette directly into the esophagus.
And Mike lived for 18 months until he died in a motel while being transported in all the united states for display in carnivals.
After his death he was entrusted to the University of Utah which should determine a clot in the carotid had prevented him from bleeding to death.
