what the hen eats—specifically, fat-soluble plant pigments known as carotenoids.
Carotenoids are naturally occurring pigments found in plants, algae, and some fungi. When a hen ingests foods rich in these compounds, her digestive system absorbs the pigments and deposits them directly into the developing yolk.
-
Xanthophylls and Carotenes: These are the primary carotenoids responsible for yellow and orange hues.
-
Natural Sources: Grass, alfalfa meal, corn, clover, and marigold petals are packed with these pigments. If a hen grazes freely on a vibrant pasture, her body processes these plants, resulting in a rich, warm, golden-orange yolk.
-
