Gender of this New Hampshire red chick?

This little guy is Bo and I really really hope he's a rooster. The wonderful employees of the feed store I bought him at helped me pick him out from among his sisters. We're hopeful that he's a rooster but his comb seems to be kind of small compared to mine when they were that age.. any ideas? He's about 2 to 3 weeks old, New Hampshire red
