Chickens, on the other hand, can lose most of their brain and still behave more-or-less the same as they did when whole.
You have a scientific source for that, anyone able to replicate the experiment? It would be incredible if costly tissue like neurons just sat there doing nothing.
There was one famous chicken that was beheaded (during a routine slaughter) just high enough to keep the brain stem intact. A clot coincidentally prevented death from blood loss, and it lived for two years as a touring attraction, before finally dying by choking. It spent most of its time attempting to preen and peck.

How big is a chicken’s brain, anyway? As Jadael notes, the brain stem was intact. How much more is there to a chicken’s brain? Also note that it hardly needed, say, its optical processing systems anymore.
