In a perhaps somewhat misguided turn that could make carnivores out of the strictest vegetarians (I'm kidding, folks), animal-rights group PETA is considering signing the polarizing Paris Hilton as its latest spokeswoman.

Playing on the fact that the Hilton Hotels (NYSE: HLT) heiress and party girl is currently spending time behind bars, PETA officials hope Ms. Hilton grows to empathize with chickens and other animals who live out their days in cramped, confined spaces.

A PETA spokesperson told MSNBC's gossip columnist that "We're asking Paris to narrate our Kentucky Fried Cruelty video showing how chickens are routinely crammed into tiny cages and suffer broken wings and legs ... unlike inmates at the jail in L.A., these animals get no reprieve or medical treatment."

The group even has the tag line sewn up "KFC - that's not hot." My opinion? That's not creative, and the Yum! Brands (NYSE: YUM) chain should have nothing to worry about. While the ethical treatment of animals is an important issue, perhaps a more sympathetic, thoughtful spokesperson would better convey the severity of the problem. KFC officials say their chicken is purchased from suppliers such as Tyson Foods (NYSE: TSN) and Perdue Farms, which are all routinely monitored for animal welfare violations.

While Paris has yet to respond, PETA is encouraged by the precedent of Martha Stewart narrating an anti-fur video after her incarceration.

Cage-free eggs are the latest forefront in the constant PR campaign of many leading retail companies to be seen as the humanest, the most animal-friendly, the most vigilant about the health of its products. As indication of the bigness of this particular buzz-phrase, several weeks ago, Burger King Holdings Inc. (NYSE: BKC) announced a switch to both cage-free eggs and pork products. So important is the issue that when Portland, Oregon fast food chain Burgerville broadcast their own switch to cage-free, local media cried, when will Starbucks Corporation (NASDAQ: SBUX) switch all the eggs in its products (including its popular breakfast sandwiches) to cage-free?

The answer could be far more muddled than (for instance) the coffee giant's recent changeover to hormone-free milk or trans-fat-free baked goods. Here's the thing: it's not necessarily assured that cage-free eggs are the be-all and end-all of chicken humanity. And the costs go far beyond a little extra space.

This is not to say that I disagree with cage-free eggs, quite the contrary: I recently began raising chickens (Bella, Mathilda and Twitter are now six weeks old, and were recently joined by baby "sisters" Gilda and Genevieve) much because of the considerable health and taste benefits of cage-free eggs. Ideally (and in my own backyard), chickens who are not confined to cages get more exercise and a more balanced diet, including greens (they love blackberry and dandelion leaves). The eggs are therefore packed with good vitamins, making the yolks more orange and the shells sturdier -- whether brown, white, or pinkish.

But not all cage-free chickens are raised equally.

If animal-rights gurus constitute a sizable chunk of the fast-food demographic, Burger King Holdings Inc. (NYSE: BKC) just scored a major victory. On Tuesday, the company announced that it would start buying eggs and pork from suppliers that do not confine their animals in cages and crates. Furthermore, according to the New York Times:

The company said that it would also favor suppliers of chickens that use gas, or "controlled-atmospheric stunning," rather than electric shocks to knock birds unconscious before slaughter. It is considered a more humane method, though only a handful of slaughterhouses use it.

The company is hoping that, within the next two months, two percent of its eggs and 10% of its pork will come from farms that allow the animals greater mobility. Most interesting, the company does not anticipate raising prices as a result of the change. The announcement comes after meetings with the Humane Society and People for the Ethical Treatment of Animals.

It will be interesting to see the reverberations of this move throughout the industry. A large company like Burger King has the power to set the bar for corporate responsibility and I would look for other restaurants, large and small, to follow its lead.

Large corporations have the power to change the world for better or for worse. If companies like Burger King and McDonald's Corp. (NYSE: MCD) decide to ramp up environmental/humane practices, they can make a big difference. Bravo to BK for doing the right thing.
