Does the color of the yolk indicate freshness?

The color of an egg yolk does not indicate its freshness; instead, it reflects the hen's diet. Hens that consume a diet rich in yellow or orange pigments, such as those found in certain grains and greens, produce darker yolks. Freshness is better determined by factors like the egg's age, its smell, and whether it sinks or floats in water. Thus, yolk color is more about nutrition than freshness.
