Today April 10, is National Farm Animals Day, a holiday meant to promote the welfare of America's enormous livestock population — including all 9 billion chickens, 244 million turkeys, 93 million cows, 65 million hogs and 6 million sheep, among others.

U.S. farm animals endure a wide range of hardships, from a lack of elbow room and exercise to an excess of hormones and antibiotics. The point of National Farm Animals Day, according to founder Colleen Paige, is "to raise awareness about the plight of slaughter animals, as well as to find homes for abandoned and abused farm animals."
