It's still debatable whether America's in the midst of a food revolution, but a growing number of the country's biggest corporations are focused on promoting natural and local ingredients.

Late last week, McDonald's announced it will take part in a study in conjunction with animal welfare groups, academics, and egg suppliers that compares battery cage-dwelling hens to free-range hens. The following day, Wendy's proclaimed that two percent of its egg purchases will now come from cage-free hens. The response from the animal rights community has been mixed. Although the Humane Society called Wendy's decision "a modest but meaningful step in the right direction," it also maintains McDonald's is only conducting the study to delay reforms in its farming practices.

Both Wendy's and McDonald's have been under fire for failing to change their practices after many other competing chains, such as Burger King, Quizno's, Hardee's, and Denny's, have already converted to using eggs from non-caged hens.

I'm happy to hear that both chains are making a concerted effort to look into free-range eggs — although it's disappointing that only five percent of eggs in North America come from free-range hens. Do you find yourself hopeful or skeptical about the chains' efforts to go cage-free?
