Day 1
This is how the egg is before incubation starts.
The blue pocket is the air space.
The yellow is the yolk and it contains the germinal spot. The germinal spot is what will develop into a duckling.
The green ropelike cords are the Chalaza. They hold the yolk in the center of the egg.
The light blue part is the albumen. It provides nutrients for the growing bird.
