This mostly depends on the species. For instance, Indian Stick Insect eggs take around six months to hatch, whereas Giant Prickly (Extatosoma tiaratum) eggs can take up to a year.
4-6 months

It doesn't stay. She lays the eggs and leaves them. They hatch and they scatter.
About 3-4 days after spawning depending on temperature.
a frog or toad lays it's eggs in water and then leaves them to hatch and grow on their own
Stick insect eggs take about six to nine months to hatch, possibly a little earlier if kept in a warm room. If the insect is well fed, kept clean and exercised regularly, it can live for as long as 1 year, 2 months and 14 days.
Turtles lay eggs in shallow nests in the sand, and they hatch there.
I believe it take 21 days for a egg to hatch It depends entirely upon the species. Insect eggs may take a matter of days to hatch. Birds' eggs may take around three weeks. The kiwi's egg has an incubation period of 70-80 days.
The osprey typically mates for life. It usually lays two to four eggs within a month. It typically takes about five weeks for the osprey's eggs to hatch.
Porcupines are mammals! They don't lay eggs?!?!
It takes 2 to 3 days for the eggs to hatch.
