Rooster or Hen

[eighthens525]

I got 10 female chicks from mypetchicken and this one I have is making me doubt whether or not she is a hen or rooster. She is 13 weeks and makes almost a crow sound in the morning but her tail feathers look like a hen. She is bigger than my other chickens and is the most bossy too. The sound is kind of crazy so just wanting some help figuring this out! This post wont let me attach a video of the sound. She's the black and white one.

I think it's a Rooster. I can see the saddle feathers and pointy neck feathers coming in. Very handsome roo!
