Watch the bluebirds closely to make sure that they incubate them. Also watch out for sparrows and other birds that may crack bluebird eggs or take over the nest.
Usually right around 2 weeks.
It takes about 3 months to hatch them.

Bad eggs are glitches and will never hatch. Sorry.
One. Although double-yolk eggs are sometimes produced, they probably never hatch.
Normally nearly all the duck eggs will hatch, although occasionally one or two eggs in the clutch will never hatch. Of course, in the wild, some eggs are eaten or broken by predators, but those that survive will should hatch, if they have been cared for properly.
Some will but the hatch percentage will be very low.
Anywhere from 10 weeks to 10 years though usually on the tenth year you know it is not going to hatch
you can never hatch a walrein egg. eggs always hatch at the lowest form. i thought everyone knew that.
100 to 200 years
The gestation period of pigeon eggs is about 18 days.
The ancient Egyptians buried the eggs in warm fresh manure.
