Breed?

My guess is an easter egger.

She is an EE.

Olive egger or Easter egger

If she came from Tractor Supply she wasn't sold as an EE because they don't list them. However, it's pretty clear that she is. Easter Egger isn't a breed but rather a fun mix where, generally speaking, the females will lay a colored egg (blue or green). It's not guaranteed though. In recent years there has been an increase in the number of mixed birds hatcheries are selling with certain traits. She is probably one of the designer mutts they've created and marketed as an "Olive Egger" which is just an EE that will lay a darker "olive green" egg. This happens when mixing a bird that lays a blue egg like an Ameraucana or a Cream Crested Legbar with a bird that lays a dark brown egg like a Marans. This would explain the feathered feet (Marans) and the muffs/beard (Ameraucana).
