Battery hens, most often refer to layer hens but can also be meat birds raised only for meat. The egg laying capacity of a layer is about two years and egg production drops rapidly from that point. Most battery operations cull their birds at about 18 months old to ensure optimum production. Birds can continue to lay eggs for about one year after the battery will no longer use them and if fed a diet high in fat called "finishing" they can be used for meat.
