I agree with Georgia Boy 1970 and Kev. The Red Sexlink is the mom becuase she carries dominant (so she would mostly likely be from a cross of a Red roo on a RIWhite hen, not a Delaware since Delawares dont have dom white.)
But that is what you would get from crossing that BR roo with a Gold Sexlink hen, if she didnt have dom white, the chick would be barred similar to the barred rock, but the dom white covers most all black so thats why it is white. I would expect it to get a little gold leakage as it grows.
