Silkie is a bit older now...

Can you get a clearer and closer picture of the comb? From the pic it looks like there is a comb forming which would likely indicate a cockerel.

Almost nothing for a comb. No evidence of waddles either. Just went out and took these photos.

That's a tough one. I'm going to guess cockerel because of the comb formation.

Yikes I'm still saying Cockerel.

yeah that looks like a roo judging by the long streamer like feathers on the head. It can be kind of hard to sex silkies because they are so slow growing.
