Why is incubation necessary for developing chick?

Incubation is crucial for developing chicks because it provides a controlled environment that maintains the necessary temperature and humidity levels for proper embryonic development. During incubation, the eggs require consistent warmth to facilitate metabolic processes and growth. Additionally, turning the eggs helps ensure even heat distribution and prevents the embryo from sticking to the shell, promoting healthy development. Without adequate incubation, the embryos would be unable to survive and grow into healthy chicks.
