Welcome to BYC. Glad you decided to join our flock. If sheer egg production is your main priority, the best layers in the world are White Leghorns (for white eggs) and Sex Links (for brown eggs). These are the hens used by commercial laying houses as they are egg laying machines. Red Sex Links are sold under a lot of different labels including Isa Brown, Gold Sex Link, Red Star, Gold Star, Golden Comet, Golden Buff, Cinnamon Queen, etc. Black Sex Links, which are my personal favorites as they are very friendly and hardy, egg laying machines, are also sold under the label Black Star. I've raised Black Sex Links for years (along with dozens of other breeds and hybrids), and they have been my best layers, consistently churning out more than 300 large brown eggs per hen per year with double yolks not being uncommon. I have especially been impressed with their egg production in really cold winter weather when my other hens stopped laying. Please feel free to ask any questions you may have. We are here to help in any way we can. Whatever breed or hybrid you decide to get, good luck with your flock.
