During egg incubation, the embryo develops inside the egg. The embryo begins to form from the fertilized egg cell (zygote) and grows into a chick (in birds) or other animals depending on the species.
The key parts of the egg that develop during incubation include:
The yolk: It provides nutrients for the growing embryo.
The albumen (egg white): It cushions the embryo and supplies additional nutrients and moisture.
The amniotic sac: This surrounds the embryo, providing protection and allowing for waste removal.

The incubation period for chicken eggs is usually 20 to 21 days, but can be up to 30 days for other poultry. During this time, a hen sits on the eggs to provide the necessary warmth for the embryo to develop into a chick.
-
During development, the embryo uses mainly the protein (from albumen and yolk) for building up the body tissues, and gets the energy needed for that process mainly from burning the yolk fat. During this process, the embryo consumes oxygen and produces water, carbon dioxide and heat.

During egg incubation, the embryo’s development begins with the formation of the heart and blood vessels.
1. First 24 hours:
The embryo starts to form.
The primitive streak, which will develop into the spine, appears.
The brain and nervous system begin to develop.
2. Second day:
The heart begins to form and starts beating around 42-44 hours.
Blood vessels spread through the yolk to provide nutrients.
-
This blood ring develops as blood vessels form and Fluid accumulates and reaches its peak at day 6 of incubation
-
The first part of a chicken egg to develop during incubation is the zygote.
