Feral chickens are seen at what is known locally as "Chicken Roundabout" in Ditchingham, approximately 10 miles (16 km) from the Suffolk farm where the deadly H5N1 strain of bird flu broke out in Holton, eastern England February 6, 2007. The cull of almost 160,000 turkeys on the farm has been completed, the government said. REUTERS/Luke MacGregor (BRITAIN)
