What kind of comb is this?

This is my 7 week-old BR (I think) chick. The comb isn't completely straight -- the top seems to have some irregularity. I'm new to chickens.... is this a single comb, or something else?

Looks like a single comb. It's just missing the last points on its comb, I had some like that.

it will be fine once it grows in
