Here are the facts: 1  More than 100 million animals are reported killed by hunters each year.  The vast majority of species that are hunted -- waterfowl, upland birds, mourning doves, squirrels, raccoons, rabbits, crows, coyotes, etc. -- provide minimal sustenance and do not require population control.
More than 9 billion chickens, along with half a billion turkeys, are slaughtered for food in the United States each year. This number represents more than 95 percent of the land animals killed for food in the country. Worldwide, more than 50 billion chickens are raised and slaughtered annually.
