a sensor activates a burst of air from an air cannon under the floor to
launch
the chicken in the air, depending on how high the chicken gets will
determine
the weight of the chicken, Use a camera to determine how high the chicken
gets.

An arm could also come out of the wall to swat the heavy chickens to the
left
and the lite ones to the right, you could use another air cannon to do this
but
would not be as spectacular as having a bat/racket swat each chicken, this
also ensures that the meat is tender.

Also because a Live Chicken would resist by using its wings it would be
possible
to sort out the dead ones from the live one, the ones that actually hit the
wall are
dead, the ones thet dont a are not, then again the ones that are dead are
not going
to be wandering onto the air cannon :).

see........ resistance IS futile
Hmmm, was that $1000 US :), thats $1800nz :)
