How do baby birds know when to hatch from their eggs?
Quick Answer
Eggs hatch when the embryo has developed enough and environmental cues, especially warmth and timing, trigger the process. The chick then uses its egg tooth to break the shell.
The Full Story
Inside the egg, a bird embryo develops over days or weeks depending on the species. Incubation temperature is crucial because it affects the speed and success of development. As hatching time approaches, the chick begins moving and using a small temporary structure on its beak called an egg tooth to crack the shell. In some species, the timing of hatching can be synchronized so chicks emerge around the same time.
