There's already enough guilt involved in gorging yourself with high-calorie doughnuts, so one major doughnut maker has decided to make enjoying a doughnut, well, a little more enjoyable. Krispy Kreme Donuts announced this month it's developed a company plan to purchase cage-free eggs over those derived from hens shoved in tiny battery cages. That's good news not only for the birds, but people, too. Cage-free eggs are up to 21 times less likely to harbor the salmonella germ. Cage-free means the birds are free to roam about and engage in many natural hen behaviors, though it does not mean that they are fed high-quality organic grain or granted time outside. Still, it's a great victory for animal welfare advocates, and one that the Humane Society of the United States is reportedly pleased about.
