Are they still "black sexlinks" if not completely black or do they have a special name?
pullet and cockerel
my beautiful EE rooster
I don't understand how this can be a black sex link because, as I understand it, the sex linked gene is the barring gene from the hen and there is no barring on a white leghorn? Maybe I misunderstood but the way male black sex links are identified is by the white spot on their head from the barring gene, whereas pullets are not barred and hence don't have a white head spot.
Perhaps you are confusing red sex links with black sex links?
