The primary factors influencing the color of an eggshell in poultry are genetics and, to a lesser extent, diet. Different breeds of chickens have genetic predispositions to lay eggs of specific colors. For example, Leghorn chickens typically lay white eggs, while Rhode Island Reds often lay brown eggs. Diet can influence shell color slightly, but genetic factors are the dominant determinants. The pigment responsible for brown eggshells, called protoporphyrin, is influenced by genetics and can be deposited during shell formation.
