1. Diet of the Hen
The primary factor affecting yolk color is the diet of the hen. Hens eating nutrient-rich diets with green plants, insects, seeds, and grains produce darker, more vibrant yolks. Hens fed mainly corn or wheat usually have pale yellow yolks.
2. Darker Yolks Are Richer in Nutrients
Deep orange or dark yellow yolks generally indicate higher levels of nutrients like omega-3 fatty acids, carotenoids, and vitamins. These nutrients come from natural hen diets, such as grasses and insects. Darker yolks tend to contain more vitamin A and antioxidants such as beta-carotene.
3. It Doesn’t Affect Taste
Despite assumptions, yolk color does not directly influence egg flavor. Taste depends more on the hen’s overall diet and living conditions. Pale yolks can taste just as good as dark ones.
4. No Indicator of Egg Freshness
Yolk color does not reflect egg freshness. Freshness depends on storage time. To check freshness, use the float test: place the egg in water — if it sinks, it’s fresh; if it floats, discard it.
