According to agricultural and food science experts, the vibrant hue of a blue egg shell is the result of a harmless genetic trait in certain chicken breeds and has no bearing on its safety or nutritional value. This article will delve into what makes blue eggs safe to eat and explain the science behind their color.

Did you know that the color of an eggshell has no effect on its nutritional value? The nutritional value of blue eggs, therefore, is identical to that of white or brown eggs, with the primary nutritional differences coming from the hen's diet and living conditions.

Despite a persistent myth, scientific evidence confirms the color of an eggshell has no bearing on its nutritional value. So, are blue eggs healthier than their brown or white counterparts? The answer lies not in the shell, but in the hen's diet and environment.

Over 500 years ago, a genetic mutation caused by a harmless retrovirus in native South American chickens triggered the accumulation of a green-blue bile pigment called oocyanin, causing them to lay blue eggs. This surprising fact is key to answering the popular question, **what are blue eggs?**
