And how conscious is the chicken with its brain stem removed?
Twaddle!

It depends where the head is removed, just on how much the brainstem remains, a chicken can run about for days before they either bleed to death or starve to death. (Mike the headless chicken lived months) stun a chicken (causing permanent damage the brain), and then remove the head, high up and the chicken does not run about. Chop off the head,( in the same place as the stunned chicken) and sometimes the chicken can move for hours.
