I'm coming from other breeds (Bielefelders and Marans) and I considering getting four 20 month old Cream Legbars. At what age do they slow down in egg production? I understand that the slower maturing breeds lay up to four years - does that seem to be true? Also, I see that cayenne pepper seems to be good for hens - any idea if I could feed them jarred peperocini that is WAY too hot for me? I hate to just throw out the jar, but I certainly don't want to harm the girls at all!!!!
