Wrong manual--you need to read Murphy's Laws as Pertaining to Hens
Rule #1 when you need your hen to lay eggs, either for breeding, or to sell, or for breakfast...she will enter a near-permanent broody state. Only hatching and raising chicks will cause her to leave this state.
Rule #2 when you need your hen to brood, hatch and raise chicks, she will remain uninterested in the process, until such time as you break down and purchase an ultra-fancy, ultra-expensive, fully-automated incubator, at which time she will revert to Rule #1.
