I was reading a book, since I know nothing personally about hatching eggs, which clearly indicated that fertility of hatching eggs decreased sustantailly in July and August. At least this applies to chickens. Does this also apply to turkeys? I'm planning to buy a tom and hen (1 yr old) soon and need to know if I should start incubating eggs. ( owner said tukey hens do not make good mothers.) I'm CONFUSED!!!! How can heritage breeds like turkeys be bad mothers????
