If you cross your B/B/S Barnevelder rooster with a barred hen on the black sex link list in the first post in this thread, you will get male chicks that are barred and pullets that are not barred. With the black rooster the chicks should be black. With the splash roo, the chicks should be blue. With the blue roo, half should be black and half should be blue. I haven’t done that cross but I think you should be able to see the spot on any of them. I’m assuming the B/B/S is based on Extended Black. If it’s based on something else, then seeing the spot could be a problem.
You cannot use a barred rooster to get a black sex link. Tadkerson is real clear on that in the first post in this thread. I don’t know of any standard breed red barred rooster, but if you have a red barred rooster (probably a mutt) that is pure for gold, and you cross him with a hen off the red sex link chart in the first post, you might get a red sex link chick. It’s going to depend on what other genetics are present as to whether you will be able to see a difference in the red down and yellow down. Since a red barred rooster is almost certainly to be a cross with mixed up genetics, I wouldn’t count on it. But you might get lucky.
There is more to chosing them than just color. Othe genes are important. That's why the breeds are listed in those charts.
