From Yahoo News:
"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."
Burger King is to be congratulated. (As are the other companies, referred to in the story below, that have made, or will be making, changes concerning their animal-related policies.)
One hopes that the Burger King plan can be achieved/implemented before 2017.
