Good eye; I completely missed the feathering on the legs of the red bird. Now that I've seen them, I agree that it's a mixed breed.I agree with the above recommendations on the Wyandottes however I believe the the last one is a mix. My first look I thought production red as well but that hen is feathered down her legs and rhode islands/new hampshires are smooth legged. Correct me if I am wrong.
