LOS ANGELES (AP) -- Game show host Bob Barker has rescued five chickens that were part of "Big Brother." "The Price Is Right" host and Nancy Burnet, an animal rights activist, went to Studio City, the site of the "Big Brother" house, on Sunday to collect the chickens, whose eggs were used by the show's participants for food. Barker and Burnet told CBS they were concerned about the welfare of the chickens used on its just-completed show. The network agreed to turn over the chickens so that they could be put in a refuge.
