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.

The restaurant chain, which serves breakfast all day, said it was adding the temporary 50-cent surcharge because the bird flu has caused a shortage in the egg supply.

Waffle House became one of the first big chains to join smaller restaurants with surcharges for egg dishes. Economists don’t see egg-price relief in the near-term.
