Nice work on the chicken build wrapped around the actual farm; would make a good prank build
Be my definitions, I'd call this fully automatic (produces infinite chickens once started), but not practical (too much wrapper around the farm proper).
Concur, however, on the fun/funny issue….
WARNING: I have an extemely "grindy" playstyle; YMMV — if this doesn't seem fun to you, mine what you can from it & bin the rest.
