Welcome to BYC. Glad you decided to join our flock. It's a mixed breed rooster; probably an Easter Egger (if it carries the blue egg gene). If you haven't done so already, definitely check out our Learning Center at https://www.backyardchickens.com/atype/1/Learning_Center. There is lots of useful information there. Please feel free to ask any questions you may have. We are here to help in any way we can. Cheers.
