What did your Hansdotter ancestors do for a living? Share Census records can tell you a lot of little known facts about your Hansdotter ancestors, such as occupation.
Best Answer: It varies by species..but most passerines (perching birds) take approximately 2 weeks to hatch their eggs, and usually another 2 weeks before the young leave the nest.
If left undisturbed, the eggs should take about 14 days to hatch. And the baby birds will leave the nest about 14 days after they have hatched. I've attached a few useful links. Source(s): http://www.learner.org/jnorth/tm/robin/F... http://animaldiversity.ummz.umich.edu/si...
