Hen or roo??

[Kirkydoodledo]

I know it’s still pretty early but I’m hoping someone experienced will be able to help me identify if my buff laced polish and white silkie are pullets or cockerels? It’s driving me absolutely insane trying to figure them out!! They are 7 weeks old today. I already know what all my other chicks are but I’m going nuts trying to sex these two! At first I thought the polish was a cockerel and the silkie was a hen but now I’m starting to think the silkie may be a cockerel and I keep going back and forth on my little polish... SOMEONE HELP ME PLEASE!!

I dont know much about this breed, but I believe it takes longer to sex them than others.
Goodness they're so cute!!!
