A chicken will typically get an iPad worth of space to itself Japan is the 3rd largest egg consumer in the world, but how many people know how these eggs are made? Layer hens in Japan are mostly reared in 'battery cages', small wire cages stacked up to maximise efficiency and have as many hens as possible in a given space. A single hen typically gets a 20cm2 area to itself, that is, their entire world is no more than a single iPad worth of space. Hens stop producing eggs after one to two years and are eventually slaughtered. （Translated by Yuhri Ishizaki）
