Bearded Silkies- What Gender?

[Chili22]

So I've got three 20 week old, buff bearded silkies. I know it's tough to tell the sex of silkies until they crow or lay an egg, but I've put a video on YouTube, with hopes that I could get some input as to what other people think of them.
I know one is a rooster for sure because there have been attempts to crow from him.

If you could note the time and the location where they are in the picture with any comments that would be great.

2:04 is a cockerel, he's been the only one to tell us what he is.

So you were definitely right about 1!
I hope at least one of the other two is a female.
