It has a beard. Not too many bearded breeds, especially combined with single comb. Faverolles is one but he is not the most common faverolles color(salmon) and does not have leg feathering so probably a mixed breed. Could be mixed with faverolles or easter egger or even a game chicken from a bearded line.
Kind of leaning towards faverolles mix because of his heavyish body, shortish legs and tail plus single comb and beard but don't think anybody will ever really know.
