Burger King makes cage-free eggs, pork promise
In a boost to animal welfare activists looking to get livestock out of cramped cages, Burger King will be the first major U.S. fast-food chain to give all of its chickens and pigs some room to roam.
On Wednesday, the world's second-biggest burger chain pledged that all of its eggs and pork will come from cage-free chickens and pigs by 2017, hoping to satisfy rising consumer demand for humanely produced fare and increase its sales in the process.
