Pullet or cockerel

[Kaybee4]

I purchased chicks the first week of June, so they’re around 12 weeks. I was told they were Lavender Orpingtons but they seem to actually be Lavender Ameraucanas. I am very curious to know if any may be a rooster, I have my suspensions. We have one other EE/leghorn mix that is a rooster and crowing but these have not yet however some characteristics seem rooster. I’m new to this though so I’m not 100% sur

I see two lavender roos, but better tail pictures would help thanks!

Check number 1's tail feathers, if they're pointy it's a he (they look like they might be pointy, but not sure).
