Hello and Welcome To BYC! You can post pictures of your chick in the What Breed/Gender forum for help with figuring out what you have https://www.backyardchickens.com/f/15/what-breed-or-gender-is-this If that is a first generation black sex link, it is a pullet, the males are barred in color.
Welcome to BYC. Glad you decided to join our flock. Your Black Sex Link is definitely a pullet. As Kelsie2290 said, male BSLs are barred. Black Sex Links are my favorites as they are very friendly and hardy, egg laying machines. I've raised them for years (along with dozens of other breeds and hybrids), and they have been my best layers, consistently churning out more than 300 eggs per hen per year. You should get loads of large, brown eggs from that girl. ) Please feel free to ask any questions you may have. We are here to help in any way we can. Good luck with your BSL.
