Silkie with green feathers Does this mean rooster?

Noticed my two partridge silkies that are 12 weeks, have both grown some blue/green feathers! Does this mean they are both roosters?? It’s weird as apart from these green colours they have small combs, haven’t crowed etc so they don’t seem like roosters! If anyone could help would be great! Here are some pictures

Feather color on silkies does not tell you what sex they are. I always have to wait until they grow up a little more to tell.
