Yes like I said in the case of black sexlinks, it is the barring in the hens that makes the sexlinks, though most people think you have to use a red roo because that is what is most commonly used, but you can use and roo as long has he is not barred, dominant white, or masking barring.
And then you have the blue gene working too, genetically speacking you are breeding blue to black, so the rough percentages should be half blues and half blacks that hatch, but since your roos will be barred becuase of sexlinkage, you will have blue barred and black barred roosters, and both of your pullets look black, but if there were more to hatch, then it would produce solid blue and solid black pullets.
