Hen or roo?

[Yocelinsaldana06]

Can you guys help me sex my 3 month old silkie chicks? I know it’s hard to sex silkies and best options are to wait until they either crow or lay an egg but sometimes a few are really obvious so I wanted to see what you guys think. How many look like they might be roos and how many might be pullets? I have 5 but I only included 4 of them because one of them already crows and attempts to mate so I didn’t include his pictures since I already know what he is.

First one looks female. The last one with the wide comb looks male to me. How do they compare in comb size to the one known cockerel?
