Actually, yolk color can be manipulated using natural ingredients. The most common additives are marigold powder and red pepper powder.
As you can see in the photo, excessively high amounts of red pepper powder will result in a RED yolk!
[ But, hey, it’s a natural ingredient! Should we try to do this for the Valentine’s special next year?!? ]
It doesn’t harm the hen when added in proper amounts, but here at Cedar Valley Farm, we also don’t see the need for it.
Our hens obtain most of their yolk color through the dark leafy greens they find in the pasture and the non-gmo corn, alfalfa and soybeans that we mix in their feed.
This is one of the biggest reasons why we have our very own, on farm feed mill: we KNOW what’s in that feed. ( and there’s no flower petals!)
So if the eggs you’re currently buying have the same deep orange color year around, know that this is a product of additives.
There’s just no way to guarantee consistency unless there’s manipulation.
