Welcome to BYC. Glad you decided to join our flock. You have some excellent layers. Thanks for posting the pic of your coop. ) Black Star is one of several labels under which some hatcheries market their Black Sex Links and they are very friendly and hardy egg laying machines that will consistently churn out more than 300 large brown eggs per hen per year with double yolks not being uncommon. 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.
