Eggs are among the most popular and nutritious foods in the world. Yet many people believe they can determine whether a chicken is healthy simply by looking at the color of its egg yolk. Social media posts often show pale yellow, golden yellow, and deep orange yolks side by side, asking which one comes from the healthiest chicken. The answer, however, is more complicated than many people think.
The color of an egg yolk is primarily influenced by what the chicken eats. Chickens that consume diets rich in natural pigments called carotenoids often produce eggs with darker yellow or orange yolks. These pigments are found in foods such as corn, marigold petals, alfalfa, grass, and certain vegetables.
A chicken that eats a diet low in carotenoids may lay eggs with pale yellow yolks. This does not automatically mean the chicken is unhealthy. In many cases, the bird is receiving adequate nutrition but simply consuming feed that contains fewer natural pigments.
