I never thought about it until today. Five years ago, when I got my batch of three Black Sex-Links and three Red Sex-Links, one of the Black Sex-Links turned out to be barred. I didn't know much about chickens then, so didn't think about it being a rooster. Unfortunately, it died, so I don't have any barred pics. However, she/he didn't have any white when it was a chick. Completely black. It wasn't completely barred either, just dark barring on the back. It was very docile as well, and the comb was the same size as the others, who turned out to be hens.
