Thinking a rooster

[Wachickens2024]

Hello!
I believe that my one of my chicks is a rooster. They are a 14 weeks old Amberlink from a coop. They were all sexed and sold to me as hens but this one is really not looking like one to me.
They get along well with all my birds even my older flock and isn’t scared of anything. I added a photo of my other amberlink that is the same age and from the same exact batch

Definitely a boy, male amberlinks are white, females are brown
