It'a really good to get different views of how flocks are managed.
When CLs first hit the scene -- people were trying to hatch first-eggs. In the UK - in one of his books Grant Brereton mentioned waiting until the hen is 2-years old to breed. In subsequent writings, I have seen 1-year mentioned. One of the reasons -- for 2-years old is that the hen has gone through her first molt - and you know what she is "really like", add to that you are building some longevity into your flock -- some chickens don't pass 9-12 months old....sometimes a congenital defect surfaces around tat time IMO. Lots of variables and lots of different goals.
Thank you for adding your input. Your view is what I usually hear from breeders - that maturity is the best for breeding for several reasons. Grant is quite a respected breeder.
