Dead chickens are seen at a poultry farm on the outskirts of Shanghai April 16, 2013. The owner of the farm said the chickens died of causes unrelated to the H7N9 virus. China's poultry sector has recorded losses of more than 10 billion yuan ($1.6 billion) since reports emerged two weeks ago of the H7N9 virus, a new strain of bird flu, an official at the country's National Poultry Industry Association told Reuters on Tuesday.
