Egg Color Genetics and Nutrition

Rafael, a second grader, asks how chickens lay brown eggs differently. Ron Cain, a poultry specialist, explains that egg color is primarily determined by genetics, similar to human hair color. He discusses research showing multiple genes influence egg color, with some breeds producing unexpected results. The blue or green egg color is controlled by a dominant gene. While nutrition can affect yolk color, it doesn't impact eggshell color.
