Charlie or Charlotte?

[Kristyh82]

We currently have nine 9-week old chickens.
I'm pretty positive about the gender and breed on some of them but others have me confused. I appreciate the help

Here's Charlie (white with red comb). I know he's a roo but I'm not sure what breed he is.
And Fabio (buff with feathered feet). I'm not sure what kind Fabio is nor if he is a he or a she.

This is Fajita (grey in the front). Americauna? Roo or Pullet?

And lastly, Houdini. Americauna? I think he's a Roo but can't quite be sure.

Deleware or Columbian Rock.
Buff Brahma
Barred Rock Cockerel
Easter Egger Pullet
Easter Egger? silver Penciled something? Pullet

Thanks! We were worried that the Easter Eggers were roos because the darker one likes to fight with the Columbian and Barred Rocks roos.
