Like a mythical dragon, tortoises tend to hatch when they think the occasion is right, especially when the planets align, a suitable caretaker is nearby, or on a blue moon. If the tortoise is retarded (like the majority of them), then it will probably hatch whenever it feels like coming out of it's little shell. Unfortunetly, the stupid human caretakers will think that the eggs are duds and will dispose of the eggs before they want to hatch.

The incubation period for a tortoise egg is around 60 to 120 days. So, give or take 2 to 4 months. However they will not be able to care for and feed themselves for the first 3 to 7 days during which time they have an embryonic sack of nutrients from which they sustain themselves until they are sturdy enough to start moving. Time of year in which the tortoises hatch depends on the species of tortoise.
