Not the right body type and not the nice dark coloration that makes a RIR a RIR.
When you look at a RIR rooster "head on" so that you can see his back, they need to look like a brick. Square all the way from the shoulders to the hips. Love to see it all the way from the shoulders to the tail, but oftentimes the tails are "skinnier" than the rest of the body.
Bama...gorgeous cock!
