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.
During the time when a female bird produces eggs, changes happen in her body that will need an aware owner to help with. An egg is made when yolk is released from the ovary into the oviduct, where it will take 3 weeks or so for the body to form a hard shell around the egg and expel it. This hard egg shell takes a lot of calcium to form, and a cycling bird will need plenty of extra calcium in her diet to help her do this.
