Gender of these 2?

Thanks for clarifying. I didn't realize they had different comb types. I just remember reading that Silkie cockerels tend to have wider combs than pullets, I guess that only applies if they're pure Silkies.

When they have the same comb type, males do tend to have wider or thicker combs than females. That can be useful if you are trying to sex a group of chickens that all share one type of comb. But it's not very helpful if there is just one chicken with each comb type because the difference between comb types is bigger than the sex-based differences within comb types.

UPDATE:

Yeah the white was a roo, and has this weird looking crest and huge waddles.

A crest is feathers that stick up on the top of the head.
A comb is the fleshy thing, usually red but sometimes black, on top of the head.

You seem to be focusing on the comb in these photos.

That looks like a fairly normal comb for a Silkie. Or maybe I should say, weird combs are normal for Silkies and Silkie-mixes

Thank you for updating. It's nice to know what the right answer actually is!
