Half-boiled eggs can't be eaten overnight. Eggs that are not fully cooked are susceptible to bacterial growth if not stored properly, which can cause gastrointestinal discomfort and flatulence. Eggs can be kept for up to 3 days, and 4-5 days in the refrigerator is not a problem; however, any longer than that and they will not be fresh, they may not smell bad, but they will not taste fresh.

Whether or not you can eat your eggs overnight is not just about whether or not they've been heated. To cook the eggs in the first boiled eggs, only in the first boiled eggs cooked, overnight and then cooked to eat is not a problem.
