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.
The embryos use their egg tooth to peck their way through the shell. This hard tip on the beak eventually falls off. Eastern Bluebirds take 1-6 hours to pip through the shell (it can take an Albatross 6 days!) It can take 24-48 (rarely 72) hours for all eggs to hatch. NEVER remove unhatched eggs until 4 days have passed since the first one hatched. Note: some people count this as Day 1. See another close up of a newborn.
