Penjelasan
Yolk (3) & Albumen (4) provide food for developing chick
Albumen is a solution of protein in water that is secreted by the oviduct of birds and some reptiles. Albumen surrounds the embryo and yolk, which it cushions within the shell of the egg. It is eventually absorbed by the embryo as food.
