We wondered what this might mean: Does the color of the yolk say anything about the chicken or about the nutritional value of the egg?

Scientific research has been done on this phenomenon.


People have said that the color and shape of an egg’s yolk can say something about the health of the hen that lays it. The general idea is that the darker, firmer and rounder the yolk is, the happier the chicken in question is. It should be a sign that this chicken had a lot of freedom to roam and also had a rich and varied diet. On the other hand, a lighter egg yolk would indicate an unhealthy life for the chicken. This information was long believed to be the truth, but it turns out to be completely false! But that leaves the question: what causes the color difference for egg yolks and what does it mean?
