Can you tell a boy by the crow at 3 weeks?

I have 2 Araucanas - one is cross beaked so I am worried about her. She's super nice. The other is super flighty, bossy and crows loudly, also her tail feathers sort of stick 'upwards' a little. I am worried I will end up with no blue eggs!!!

crowing is usually sign of a rooster.. and those feathers.. sounds like a roo to me.

Any small skinny feathers that hang down near the tail? Those are saddle feathers.. another dead give away

Could be a roo, but could also be a bossy little pullet. Do you have a picture?
