Help identify the genders of my Silkies please.

[Coopmeister1]

 

[FuzzyCritters]

The one in the middle looks like a roo because of the bright red comb. Don't know about the others.

 

[LittleBigBantam]

The bottom one looks more male to me

 

[JadeFarms]

The middle is a cockerel and the bottom one probably is because he seems to have streamers.

Thinking pullet, then cockerel and I'm not sure on the last one. Can you get side view of the crest?
