Bird flu has killed millions of hens in recent weeks, shrinking the supply of eggs and hiking up prices at grocery stores.

Summary

Egg prices have surged, with a dozen large Grade A eggs averaging $4.15 last month, a 37% increase year-over-year.

The rise is driven by bird flu, which killed over 16 million hens since December, reducing supply.

The Midwest, a key egg production region, has been hit hardest due to migratory bird patterns and a new strain affecting dairy cattle.

Other factors like holiday demand and rising feed costs also contribute.
