Gender on 11 week old chicken

[Beki]

Hi all, thanks for taking the time to help!

I bought these 3 chicken as pullets but am starting to get worried I received roos. I think I'm hearing the start of crowing, but it's not consistent and I've heard that females will crow too. Any thoughts based on these pictures?

3 is the only one that *might* be a pullet, but I'm leaning cockerel. The fibro makes it more difficult to tell. The other 2 are definitely males.

Agreed! #1 & #2 are cockerels. I can't tell with #3.
