Hi David, I'm wondering if there is a breeder that gets 90% or better ,         
solid brood patterns.I would like to know if anyone has had a consistant        
source of solid laying queens.There has been plenty of work done on the         
genetic factor of egg laying. Dr. Rinderers book, Bee Genetics and              
Breeding, goes in depth into sex determination and mating designs. I            
wonder how many follow it in practice..                                         
 Best regards
