4 week old chick gender?

[LittleBigBantam]

My lone chick that I hatched is now 4 weeks old and still healthy. He is a white leghorn/grey and blue splash silkie(roo). I need help determining the gender though. His comb is grey instead of pink/yellow so I cant use leghorn pictures to sex him. Can any body help?

   Okay! And because She is a lergorn/silkie do you think I should suspect lots of eggs or not?

It all depends....I have a Silkie mix that lays 5-6 eggs a week!
