Crossing a buff, red, BBR, black, or blue rooster with a barred/cuckoo hen will give a sexlink where the males hatch out black with the white spot on the head and the females will be solid black at hatching. The welsummer x maran cross will look just like other black sexlinks, some people have said that the roosters from that cross look more crele but I havent noticed a difference.
So to summarize- roosters will hatch out like a barred rock and will feather out barred with some red or gold in the hackle, saddle, and wing bow. Females will hatch out solid black and will mature to be from solid black to black with red/gold on them.
Hope that helps.
