Chicken

Chickens are the mutated descendants of long-domesticated birds that lived before Great War.

Background
Some chickens survived the Great War sheltering in bunkers. In Appalachia, they have survived in a more natural fashion and are considerably more common. Less mutated than other creatures in the area, they are utilized for food.

Radchicken variants have been exposed to high levels of radiation, leaving them atrophied and naked. They are slightly smaller than their pre-War ancestors, and likewise pose no threat.

Appearances
Chickens are mentioned in Fallout 2, Fallout 3, the Fallout: New Vegas add-on Old World Blues and Fallout 4. Live chickens appear in the Fallout 4 add-on Far Harbor and in Fallout 76.
