I have to say Sexlink rooster. I had 5 in a project, and all of them had at least some black in their tails...

A Red Sexlink will have a black tail if it was from a red columbian rooster and a silver columbian hen. Not all Red Sexlinks have dominant white. If he was from a silver factor dominant white hen and a rooster that was pure for gold then he would have a white tail.
