What breed of bantam chick is this?

[MysteryChicken]

Hi so I thought this was a a black bantam silkie but I don’t think it is anymore. I think it’s a black bantam Cochin. Tell me your thoughts. It’s 3 and a half weeks old. He/she is the sweetest chicken I own.View attachment 2768798View attachment 2768799View attachment 2768800
