Will my silkie rooster get bigger than my hens?

[Alex15]

All my chicks are 13 weeks old now, I have 1 silkie rooster and 7 hens - 2 australorps, a sussex, a wyandotte, 2 welsummers and a tiny silkie hen. Other than the silkie hen, will my silkie rooster ever be bigger than my other hens (who I think are all quite large breeds, except the welsummers being medium)!?

My poor little Rusty (silkie roo) is half the size of my light sussex yoshi and he is not the boss at all. I'm wondering if he ever will be? And will he be able to mate the other hens if they don't squat for him? I wasnt planning on having a rooster and I would kind of prefer if he didnt mate my hens so much, or is at least nice about it! I caught him pulling the girls' combs a couple of times (while they were sun/dirt bathing lol), but I figure he's to small to even consider mating them!

No the silkie won't outgrow your hens. Silkies tend to be small. How old is he
