The stats you gave don't sound very big?
6lbs is about average for a typical Large Fowl hen, and 8lbs for roosters. Leghorn hens run about 4 lbs +/-.
His height and wingspan sound normal.
I'd call his shank color white, or depleted yellow. The latter happens to the Leghorn hens after a long laying season, as the carotenoids from certain foods are used in egg yolks. It's possible a rooster raised without access to many of those foods could lack the carotenoids to color his shanks.
He may be a California White? Which are half Leghorn, bred for production.
