The Department of Agriculture warned egg prices may increase more than 20% this year, after December saw a year-over-year increase of 36.8%.

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.

Egg farms are still recovering from the 2022 outbreak but now there’s also the cage-free law, mutations and competition as bird flu devastates other states.
