The year of the rooster looks set for a gloomy start. Egg prices are soaring and new year’s festivals are being canceled as South Korea fights its worst bird flu outbreak in a decade.

South Korea’s government said Tuesday that about 26 million head of poultry will be culled by Wednesday, including about one-third of the country’s egg-laying hens, after the H5N6 strain of avian influenza was found in farms and parks.The highly contagious influenza has spread to all provinces including a major park in south of Seoul and a scenic wetland area in the south.The government plans to subsidize shipping fees and temporarily lift tariffs on imported eggs to ease shortages. Officials said the government might buy eggs from overseas if prices continue to rise.

It all spells an inauspicious start to the year of the rooster, or chicken, according to the Asian zodiac.

One of the most popular end-of-year activities in South Korea is to climb a mountain or visit the seashore to watch the last sunset of the year or the first sunrise of the new year.

Each year, hundreds of thousands of people gather in the eastern county of Ulju in the city of Ulsan to watch the sunrise from a seaside park. That event will not be held this weekend, the county said, one of many festivities cancelled to minimise the risk of the flu spreading.
