I just hatched out my own Black Sex Link chicks by putting my Black Cochin roo over my Dominique and Dominique cross hens (all my hens are barred). I think you can get black sex link chicks by putting any solid color male (except dominant white male, like a white leghorn) over any barred hen (dominique, barred rock, Cuckoo maran, etc).
