Trying to figure out what I have

[Rebeccafortier]

I have a solid black chicken who I think is a roo that I got from tractor supply. He is now 14 weeks old just can't find any where online on what breed he might be

Looks like a Sumatra to me

 

[Gray Farms]

Not a Sumatra. Looks like a Swedish Black to me.

Is he completely black in his mouth
