gender help 12 weeks

Hello! I’ve attached photos of my 4, 12 week old Australorps (that’s what we were told they were anyways) and I was wondering if anyone could tell me if they are roo’s or hens? I have a feeling 3 of them are Roos but I don’t know too much about sexing! They have colour identifiers on their feet :)

Just updating pictures of my hopefully pullets 12 weeks. Breed for two are RiR mix i believe
