I've always hatched eggs with a temp range of 78-82; at that range it depends where the animals originated. Upper midwest animals usually would hatch at around 48-55 days, Colorado snakes usually would go at 54 days like clockwork, Canadian snakes at 57-61 days. Pines always took the longest to hatch at around 59-65 days, Gophers at 55-61 days. An incubation of 74 days does seem like a long time; when hatching times are long my experience is that all eggs you're incubating will be late, regardless of genus. The third egg on the top doesn't look good.
