My first hatch rate last year was about 65%. I talked to someone recently who said their hatch rate was 50%. Those rates seem low to me. I know my problem was probably that the hen was sitting on too many eggs - 16. No wonder. But I don't think that was the case with this other person, and she was wondering why her hatch rate was so disappointing low. Any ideas on why a hatch rate might be low, or ways to boost it? These are hen-hatched eggs, not incubated. Maybe hen-hatched are just lower than incubated anyway.
