Help Sexing Frizzle Chicks

[FrizzleFeathered]

I have recently got frizzle chicks which are now 6 weeks old. Two of the frizzles already have curly feathers, while the third look like a regular chick. The curly feathered chicks are aggressive and peck at my other chicks. The largest curly feathered is significantly larger too. Does this mean it is a male?

Welcome to backyard chickens!

Aggression and size don't always mean male. Do you have pictures of them? Usually if they have a red or pink comb fairly early it's a male.

Please post pics of their combs.
1 in 3 frizzles will be smooth. It's just how the genetics go.

Thanks! And no I don't have any pictures but the chick did get a crest atleast a week earlier than the others.
