Do you know if he's suppose to be a purebred? I think he's a mix, with pink legs my thoughts would be a speckled Sussex mix, perhaps mixed with brown leghorn or welsummer.
Ok cool well he's still pretty and quite friendly for a Roo! My husband picked them up from a feed store out of a bin of several different breeds we were told that we could tell what he was when it was grown! Lol!
