The frizzled serama is a rooster.

100%

frizzle is a little dude, the others are a little hard to tell, especially the silkies

 

[HorseGirlAbby]

Yeah, the frizzle is a cockerel, as the others have said. The Silkie on the right in the second pic I suspect is a cockerel as well, and at least one of the Ayam Cemanis. It's too tough to tell with the others right now.
