Welcome to BYC. Glad you decided to join our flock. I agree with TwoCrows; with that dark barring, it looks like a pullet to me.
) If you haven't done so already, definitely check out our Learning Center at https://www.backyardchickens.com/atype/1/Learning_Center. There is loads of useful information there. Please feel free to ask any questions you may have. We are here to help in any way we can. Good luck with your flock.
