He's a Columbian Rock non-typical to the breed though because of the rusty red bleeding through. I think its referred to as being brassy.
A lot of hatchery Col. Rocks and Delawares are like this from the hatcheries. They will cross them(Columbian males) with a red type hen, i.e. RIReds or NHs to cheat to keep up with the order demands for these types of chickens so therfore you get the off non- typical color pattern like the roo in question.
He's still a pretty boy though I just love the feather patterns on columbian and Delaware birds. Pretty white with a little black thrown in so they aren't a solid white color.

TheFarmMamma sure you can bred him to the sex-link girls, will make some very interresting combos. My bet is you'll have a lot of whites in the mix and should be pretty good brown egg layers. I'd be interrested in seeing some results from this type cross.
