Bantam Cochin; The usual question on gender

[ChickenRaiser95]

I bought a bantam cochin and a silkie a few months ago, and was pretty sure that they were both pullets. The males that were with them had large bright combs already. Here are the "girls" when I bought them (they were missing a lot of feathers on their backs.)
.


Each week though, I have been questioning the gender more. I really would like to know. I honestly have no idea how old they are either (maybe someone can tell from the silkie.) I have had them almost 3 months now. Here are pictures of them now.





Please help.

I would say if that cochin's comb and waddles get any bigger than that would be a boy. As for the silkie, you're on the look out for "streamers" : see these hair-like feathers that are longer than the others? That's a sign of a male.

Thanks. The picture I have of the bantam cochin is a couple weeks old now. The comb and wattles are bigger and it has a rooster tail, so you're probably right. The silkie hasn't changed.
