The easy way to tell if your eggs came from a sick chicken

2. The color of the yolk

Light or bright yellow is not the perfect yolk color, although it’s probably the yolk color people usually see. A healthy egg has a deep orange yolk.

3. The thickness of the yolk

Egg’s quality can be also determined by the thickness of the yolk. Healthy egg yolks are rounder and thicker.

Researchers report that healthy nutrition is key to producing healthy eggs. For example, the amount of beta-carotene can be increased if the chicken is fed with more beta-carotene.
