It is a hatchery-quality Spangled Russian Orloff. Traditionally Red Sex-links do not have muffs or beards (although I suppose it could be done), or at least those offered by hatcheries. Additionally they usually have a single comb as opposed to the Orloff's raspberry comb. They are considered a rare to uncommon breed. I used to have several and enjoyed them immensely.
