I read a lot about things that interest me. Often it leaves me wanting to scream. Today it is short legged lethal factor. One source denies it exists-a second source says that if short is bred to long no lethal factor-another says that 25% will die-two sources said only two percent of embryos will die. With my short legged serama rooster 50-60% DIS. Recently I switched roosters (long legged) and the first clutch has 9 out of 10 eggs living; the 14 day will be Thursday. Can someone tell me with certainty (1st hand experience) how the lethal factor works?
Hens go broody when you don’t want them to… and won’t go broody when you do.
