The birth story of a bird is amazing to many people. They start as pretty little eggs securely hatching in a nest. How long does it take for bird eggs to hatch? Well, the incubation period of these eggs varies greatly between species. On average, this period is between 10 and 30 days. Most of the time, the mama bird warms her eggs by sitting on them while the papa bird provides food for her. We’ve got all you need to know about the nests and incubation period of your favorite birds.
What’s First? The Chicken Or The Egg?
All birds start the same way. They are all little eggs before they hatch and are ready to face the world. Incubation begins after the egg is laid. This means there is heat added by the parent, usually by molting feathers to expose the lower abdomen’s skin. The species of the bird depends on the length of the incubation period. So, why does a chicken egg not turn into a baby chick? This is because eggs are very sensitive to changes in the temperature. If the temperature is too low or too high, an embryo will not develop correctly. The parents must pay a lot of attention to their incubation period.
The Baltimore Oriole flies to the north during the warmer months to lay their eggs. They like to build their nest in the middle of a tree full of leaves. You’ll often see these birds nesting high in your tree or in open wood areas. The male oriole will guard the nest while the female builds it. This nest is made from things in nature like bark, grass and sometimes horsehair or twine.
The nest gently hangs from the branch. It’s usually about four inches deep. It will have an opening at the top with a bigger chamber at the bottom of the nest for the eggs.

How Eggs Hatch
Many baby birds have special muscles and a “hatching tooth” that help the baby to move their head with enough force that cracks the egg open. Some stay in their nest for a little bit of time, while others stay nestled for months. Some birds like cranes and waterfowl are already ready to follow their mother around her land.
There is no rhyme or reason for a hatchling’s incubation period. Many different species have varying times. In most species, it’s up to the female bird to sit on her nest keeping her babies warm and cozy. Most parents also stay with their hatched babies until they learn to fly.
