Are these silkies silver and gold based or something else?

Just as an update, the two NN ended up being white cockerels. I rehomed them. And the one frizzled silkie is a pullet and she’s still here with me. So they for sure weren’t sex linked by color.

Thank you for updating. It's nice to know the answer to the original question, even though you had to wait for the chicks to grow up to know for sure!

The pullet you kept is really pretty
