drop sand and gravel on them to slowly suffocate them

Make the baby chicken live under lava so it will burn when it grows

Make the container a small as possible and put a block of lava on top of it to slowly burn the chicken and all the eggs gathered will be sorted into three categories. The first will thrown back at the chickens damaging the chicken and sometimes increasing the amount of chickens in the small space.
The second will drop the baby chickens in a small pool of water in front of the adult chickens where the baby chickens will swim in till they get tired and then drown as the other chickens watch. The third will be put in a pen where the only food is chickens and the only water in chickens blood and after 1 year the cannibalistic chickens will be scattered throughout the first and second area to feast.
