Our Osprey's at Osprey House Environmental centre in Dohles Rocks Queensland Australia, laid an egg on the 22nd and a second on the 25th May 2009 with one egg still active. We have been told that gestation is between 38 and 40 days, so here is hoping that we have a chick late June or early July.

The Gestation for a painted turtle is 20-340 days. In some rare cases the eggs may not hatch until the next spring. The turtles may also spend the winter in their nest. …The average is 70-80 days from when they were laid.
Approximately 2 weeks. Then they fledge (leave the nest) but for another 2 weeks the father trains them how to survive. 40 days
The gestation of sparrow eggs is 10-15 days and incubation is shared between the parents.
I believe it to be 35 days from the lay of the last egg.Hope this helps
Mockingbirg egg gestation is 12 - 13 days. Young fledge 11 - 13 days after that.
14 days seems to be the correct answer. I have watched the Robins build their nest starting April 5, and I am watching them feed the babies today May 4th.
cowbird gestion, according to Cornell University's Ornithology Dept., is 10-12 days.
11 to 13 days
about two weeks
24 to 72 hours :)
The gestation period of pigeon eggs is about 18 days.
Yes, they take turns keeping the eggs warm for approx. 5 weeks but eggs can also be deposited days apart.
