15 week old light brahma - male or female?

[ChickenWitch1]

This brahma is 15 weeks old and it came from a pullet bin. It has had no signs of being a male until now, it just crowed this morning? I immediately assumed it was a boy, but then I looked it up and saw that hens will sometimes crow, especially the “alpha females” of the group, and this one is definitely very dominant. So, does anyone have any idea based on the pictures?

He's a boy. The telltales are the big red comb and those pointy neck feathers. Should be a big, handsome fella if you can/want to keep him.
