Lavender Orpington chicks week old sex

[Ellydee]

I picked up 3 chicks locally, and was told he would buy back any cockerels. I know lavender orpingtons are hard to tell what gender early on, but I can clearly see a difference. Can anyone confirm by these pics?

They're only a week and a half old, correct?

They look too young to sex right now.

See a difference in what? Amount of wing feathers?
I wouldn't rely on that. Gonna have to wait imo.

The first one and the third one are males
