Why is the egg yolk more yellow in free range eggs?

The yolk of free-range eggs is typically more yellow (or even orange) than those from caged hens for a couple of reasons:

* Diet: Free-range hens have access to a wider variety of foods, including green grasses and other plants. These plants contain carotenoids, pigments that give them their vibrant colors. These carotenoids are deposited in the yolk, making it appear more yellow or orange.

* Sunlight: Free-range hens spend more time outdoors, exposing them to sunlight. Sunlight helps the hens convert some of the carotenoids they eat into the form that makes the yolk more yellow.

It's important to note that color is not always a reliable indicator of the quality of the egg. Factors like breed, time of year, and even the hen's age can affect yolk color.

Here's why the yolk color doesn't always mean a better egg:

* Nutrition: While free-range eggs may be higher in some nutrients, this isn't always the case. The difference in nutrient content between free-range and caged eggs can be minimal.

* Taste: The color of the yolk doesn't always guarantee a tastier egg.

The color of the yolk is often a marketing tool used to convince consumers that free-range eggs are healthier and better. However, it's important to consider the overall quality of the egg, including its freshness and the farm's practices, rather than just focusing on the yolk color.
