Pullet or roo

[Vanval]

Any ideas? They are 7 1/2 weeks old.
White one is more timide, follower. Brown acts like a protector but they started "chest bumping" like two bros . Also, the brown one does not like when my 5 week old silkie approaches, it runs after it or pecks it's head. They have characters that can go both ways

The white one is probably a cockerel , it might be too early on the partridge one.

With those bright red wattles the White one is a boy. The Brown could go either way.
