I think my 16 week old speckled sussex x brahmas are roos?

I was gifted 4 speckled sussex cross brahma chicks at 3 weeks old unsexed. I believe these three are roos? I have no experience in this breed so im very unsure. Thank you

I think the bird in the first photo is a pullet because I don't see any male specific feathering on her. The other two are cockerels.

Here's another photo of the first chicken just after shaking. It has long neck feathers like the other two roos but not as long i dont believe? Thank you for your reply also!

Could be a cockerel. Maybe someone else will reply with a second opinion on this bird. I'm not quite sure myself.
