The Waffle House restaurant chain is putting a 50 cent per egg surcharge in place due to the biggest bird flu outbreak in a decade.

The 24-7 restaurant said that the resulting egg shortage has led to a dramatic increase in its costs.

Bird flu is forcing farmers to slaughter millions of chickens a month, pushing U.S. egg prices to more than double their cost in the summer of 2023. And it appears there may be no relief in sight with Easter approaching.

The average price per dozen eggs nationwide hit $4.15 in December. That’s not quite as high as the $4.82 record set two years ago, but the Agriculture Department predicts egg prices are going to soar another 20% this year.

“While we hope these price fluctuations will be short-lived we cannot predict how long this shortage will last,” the company said.

China announced retaliatory tariffs on select American imports and an antitrust investigation into Google on Tuesday, just minutes after a sweeping levy on Chinese products imposed by U.S. President Donald Trump took effect.

Trump planned to talk with Chinese President Xi Jinping in the coming days.

“It is being scheduled and will happen very soon,” White House Press Secretary Karoline Leavitt said Tuesday.

China said it would implement a 15% tariff on coal and liquefied natural gas products as well as a 10% tariff on crude oil, agricultural machinery and large-engine cars imported from the U.S. The tariffs would take effect next Monday.

“The U.S.’s unilateral tariff increase seriously violates the rules of the World Trade Organization,” China’s State Council Tariff Commission said in a statement. “It is not only unhelpful in solving its own problems, but also damages normal economic and trade cooperation between China and the U.S.”
