Not quite. The chick should have only one copy of ig, and since it's a completely recessive gene, it would have no effect.
So S/S+ and Ig/ig. You'd get gold leakage, but even if you bred him to a citron female, only half of the offspring would be citron.
EDT: Silver does dilute gold, when there's a copy of each present, (see golden vs gold duckwings) which is why my research turned up that several people believe that citron roosters exist, but citron hens do not. Your roosters might even look like patchy citrons when they've fully feathered. The hard work is going to be getting a citron hen.
