Behind the Myth: Cage free Eggs.
See the complete slideshow at http://www.humanemyth.org/cagefree.htm

Hens used for egg production come from hatcheries, where male chicks (none of which can lay eggs) are killed immediately after hatching. Each year, hundreds of millions of these vulnerable beings are suffocated or ground up alive to produce fertilizer or feed.

Chickens used to produce eggs, including eggs labeled "cage-free," have their beaks forcibly mutilated to minimize the damage they cause each other when crowded together.

At all farms, large-scale and small-scale, laying hens are killed when their production declines, typically within two years, as feeding these worn-out individuals cuts directly into profits. Often the bodies of "spent" hens are so ravaged that no one will buy them, and they are ground into fertilizer or just sent to a landfill.
