That's a light brahma, right? I think it's a pullet. Here's another thread, where it shows a cockerel at 9 weeks. The wattles are a lot larger than yours, and the feathers are more pointed.

Yes Happy is a LB, sorry I did not post that. The face and comb are alot more red than the others which leaves us to question. I hope Happy is a pullet. Thank you.
