Hatchery black sex links are a red rooster over barred rock hens, that gives them the red bleed through, from just a touch of red at the throat to the entire neck and chest. You're right there. The males hatch with the white headspot, that is a genetic indicator that the bird is barred. Those males feather out barred. The females hatch with a solid black head (often a white belly) and feather out black with the red throat/chest.Thanks Donrae...
Okay...trying to remember/learn the genetics here...
I get the gold/red over the white....that's the red sexlink which creates white/pale yellow male chicks and the gold based/red females.
And I can understand a barred roo over non-barred hen gives the males the white dot (barring) and the females remain all black.
Question....what causes the typical Black Sex link where the males are barred and females are black with red bleed through. I thought you had to have a gold tone on the roo's side and a barred on the hen's side. Am I correct?
My error would be considering the Black Copper Maran a gold toned bird? It is considered non-barred? and thus over a barred hen to produce the white dotted (barred) males and the black females which would have no red bleed through?
Thanks. Just trying to learn better genetics (and keep it straight in an aging head).

However, any non-barred rooster (pretty much) over a barred hen will give sex link offspring. I've seen offspring of a buff Orpington roo over BR hens and the hens are gorgeous! They're a gold color in front, speckling kind of to black on the back end, just really pretty birds. This female might wind up solid black, or with some copper on the collar, I'm not educated enough to know. I just know she didn't have a white head spot, thus she doesn't have the barring gene, thus from those parents she's female.
Have you seen that massive thread on sex link breeding in the breeds/genetics section? He did a great chart showing all the sex link crosses, pics of chicks, etc. My genetics knowledge is pretty superficial, I don't know the genetic names of the colors and stuff, but even I can understand it. It may be a page or two back, it gets buried sometime. I think the username of the OP is tadkerson, if you want to search for it. Great info!
