Yolk color reveals a lot about the chickens and their health. And for the majority of eggs on our table, the diagnosis is not exactly ideal.

Most hens have not seen the sun, all their life, they spend 24 hours a day cooped up in a cage. Neither the “domestic production” does not guarantee that the hen is eating grain in the yard freely. Want to know if your chicken was a prisoner or a roamer? Just look at the yolk.

Most of the eggs purchased in the store look like a yolk in the middle – a thin, pale yellow yolk reveals that the chicken probably wasn’t eating a healthy diet.

Although it seems strange, thick dark orange yolk is very desirable. “Free-range chickens have a chance to eat food with the pigment and the pigment is then transferred to the egg,” explains Dr. Hilary Shallo Thesmar , director of food safety programs for the Egg Nutrition Center (ENC).

The ratio of macronutrients (fat and protein) remains the same, regardless of color, darker yolk is often a sign of xanthophylls and omega 3 fatty acids in the hen’s diet.

The hen eats xanthophyll which is beneficial for circulation, with leafy vegetables like spinach and kale, and omega 3 fatty acids with flax seeds and sea kelp.

News, which conducted its own egg analysis, and a more recent Pennsylvania State University study, pastured eggs contain higher levels of vitamins A, D and E. In addition, a healthy egg is richer with beta-carotene and omega-3 fatty acids.

Actually, all this means is that a pastured egg is better for you, as well as the chicken who lays it.
