Welcome to BYC. Glad you decided to join our flock. You have some great layers. Are your sex links Black Sex Links or Red Sex Links? I've raised both of 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. 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.
