Posting this on a silkie thread will help you more here's a few links:
I no very little about silkies so I could be completely wrong, but I think that you have a blue silkie cockerel with gold leakage. Leakage is not unheard of, and he looks like many pics I've seen. Calico, as far as cochins go, is just overly white mille fleur. Again, this info could be totally off the mark, it's just what I thought.
