Put it in the fridge. If you are hatching it, then use an incubator.

Macaroni salad with egg should be good for three to four days.
An egg taken directly from the fridge should be boiled for about 7-9 minutes to achieve a firm yolk and fully cooked white.
2 days if you keep them in fridge. Just break them and smell, also look how the yellow part is distributed. If nothing seems wrong it is ok.
Cooked eggs can last in the fridge for up to 7 days if stored properly in an airtight container.
