There are hatchery RIR's that are lighter red, alot of the time they are rust colored. They dont really have their own type, they are just red birds with a single comb and yellow legs that lay brown eggs. Then there are "heritage" or show type RIR's. With alot of the show type RIR's they are a deep dark mahogany red, some look black with a red tint, they are something else when compared to hatchery birds. The show RIR's also have their own type that meets the standard. Overall they are brick shaped with the males having a tail of 10 degrees and females with a tail angle of 20 degrees. They have brilliant yellow legs and nice medium combs, they come in single comb and rose comb. Also I remember reading in the APA that the RIW's are considered a seperate breed, they have leghorn, wyandotte, rock, and maybe RIR if I remember correctly. The RIW's are taller from what I have seen and they have to have a rose comb.
