| Rows and rows of living animals crammed together. | In Brazil, tens of millions of egg-laying hens are crowded into small wire enclosures known as battery cages. Battery cages are so cramped that hens confined to them are unable to perform many important natural behaviors, including walking, perching, dust bathing, nesting, or even fully stretching their wings. They suffer psychological stress as well as numerous physical harms, including bone weakness and breakage, feather loss, and diseases. Standard industry practices, such as slicing off parts of beaks without painkillers and manipulating the hens’ laying cycles by starving them, cause the birds significant pain.
