Egg yolk colour can vary depending on the type of feed a hen receives.
A hen fed a wheat-based diet will typically produce a pale yellow yolk, while a corn-based diet results in a deeper yellow yolk. Yolk colour can range from pale yellow to deep orange, but it does not affect the flavour, nutrient content, or quality of the egg.
Regardless of the feed, farmers work closely with nutritionists to ensure laying hens receive the vitamins and nutrients they need for optimal health.
