Egg Pigmentation and Production Process

Bird eggs development process is something that complex and amazing way how nature works. During the last few hours before the eggs laid, they can obtain unique color and patterning. Pigmentation process could be happening because there is genetically program that creating majority color and spotting of the eggs. Egg color that produce reddish-brown and blue/green shares is also created by pigments. Bird diet and health could be inluence a pigments quantity and type.
