To make Salmon you need Wheaten, Mahogany, and Silver. Yes, Silver in a male will not give a red sex link.
Oops, my bad. I guess my dyslexia kicked in and I inverted the hen/rooster catagiries. I did use a Salmon over barred rock hen and got a Black Sex Link. So u guess I got to thinking of a Salmin as the Red rooster over Silver hen thing.
* why does spellcheck change barred rock to barred Rick? Does it to me nearly every time.
