prob better ways to go about this but i choose the crazy idea
add ability to chop off a chickens head body will still run around and die eventually as normal with out head of course
well ther chould be the very low chance the head survives also and when this head is in desk to study it will alert you someone in on your claim with permissions thing to control alerts (will alert nomatter where owner is even across the world mabye even only a few times before it dies withering with each time for visible indicator and the amount of use is low but random so youll never know when it will acually run out)
it chould also die eventually but on even rarers chances it survives for longtimes (can be spotted cause the body stays alive far longer also)
