Despite the common belief that a darker egg yolk indicates a healthier chicken or a more nutritious egg, yolk color is primarily determined by the amount of carotenoids in the hen’s diet. While natural pigments from foods like grass, alfalfa, or marigold petals deepen yolk shades to orange, feed additives can also artificially alter color, making appearance an unreliable gauge of quality. Regardless of whether a yolk is pale yellow, golden, or deep orange, eggs retain similar core nutritional benefits, offering essential protein, vitamin B12, vitamin D, selenium, and choline.Ultimately, factors such as feed quality, housing conditions, hygiene, and freshness are far better indicators of an egg’s overall quality and safety than its visual shade.
