The color of the egg shell comes from the final process of egg processing in the hen's reproductive tract - the pigment secreted by the uterine epithelium, such as egg porphyrin providing brown, and biliverdin providing green. The exact pigment secreted first depends on the genotype of the hen. Secondly, it depends on the acquired factors such as the diet and health of the hen.
