The Waffle House restaurant chain is putting a 50 cent per egg surcharge in place temporarily due to the biggest bird flu outbreak in a decade. The Georgia company said that the resulting egg shortage has led to a dramatic increase in its costs.

Waffle House announced it will be adding a $0.50 surcharge to all egg items on the menu sold at its more than 2,000 locations because of soaring egg prices caused by the bird flu. The surcharge went into effect Monday.

U.S. diner chain Waffle House has added a 50-cent surcharge for every egg in a customer’s order, the company said in a statement posted in its restaurants on Monday.
