We&#039;ll explain the origins of shell color, why brown eggs are generally more expensive, and what you should really pay attention to when buying.<\/p>\n<p> To sum it up<\/p>\n<ul>\n<li> <strong>Shell color<\/strong> \u2014 this is a genetic characteristic of the breed: for example, Leghorns lay white eggs, and Rhodesian Reds or Plymouth Rocks lay brown eggs.<\/li>\n<li> <strong>Nutritional value<\/strong> The nutritional value of white and brown eggs is almost identical \u2013 this is confirmed, in particular, by the US Department of Agriculture (USDA).<\/li>\n<li> <strong>Yolk color<\/strong> depends on the pigments (carotenoids) contained in the food, and not on the color of the shell.<\/li>\n<li> More important than color is <strong>markings on the shell<\/strong> (0\u20133) indicating the breeding method and the date of reaching minimum hardiness.<\/li>\n<\/ul>\n<h2> What determines the color of an eggshell?<\/h2>\n<p> The color of the eggshell is determined by the chicken&#039;s genes. Breeds such as <strong>Leghorn,<\/strong> lay white eggs, and <strong>Rhode Island Red, New Hampshire, and Plymouth Rock<\/strong> \u2014 brown. A simple rule is often given: hens with white earlobes lay white eggs, and hens with red earlobes lay brown eggs. However, this is only a guideline, not an ironclad law.<\/p>\n<p> Each eggshell is composed primarily of calcium carbonate and is white in nature. Its brown color is due to <strong>protoporphyrin IX<\/strong> \u2013 a pigment formed as a result of heme metabolism and deposited on the shell during the final stage of its formation in the oviduct. Chickens that lay white eggs do not deposit this pigment on the shell. Some breeds also lay blue or greenish eggs (for example, the Araucana) \u2013 a different pigment is responsible for this hue., <strong>biliverdin<\/strong> .<\/p>\n<p> The shade of brown is variable. Research shows that the shells of older hens become lighter because the eggs are larger and the pigment content does not increase proportionally. Lighter shells do not necessarily indicate poorer egg quality.<\/p>\n<h2> White or brown eggs \u2013 which are healthier?<\/h2>\n<p> None. According to the U.S. Department of Agriculture, the nutrient content of white-shelled and brown-shelled eggs does not differ significantly. Protein, fat, vitamins, and minerals depend on the hen&#039;s diet and care, not on the shell pigment. For example, hens exposed to sunlight may lay eggs with higher vitamin D levels than hens kept indoors, regardless of egg color.<\/p>\n<p> <strong>Taste<\/strong> It&#039;s no different. The egg&#039;s taste is influenced by its feeding and freshness, and in the kitchen, by the cooking method.<\/p>\n<h2> Why are brown eggs more expensive?<\/h2>\n<p> The difference in price, if any, is mainly due to <strong>production costs<\/strong> . Hens that lay brown eggs tend to be larger and consume more feed, while some brown breeds lay fewer eggs per year. Demand also plays a role: in Poland, many consumers associate brown eggs with a &quot;rustic&quot; origin and a more natural appearance, although shell color does not indicate the type of farming.<\/p>\n<p> In Germany, the situation is interesting: breeders are increasingly switching to white hens. The reasons cited include their lighter weight and longer egg-laying period, but industry representatives note that the egg taste remains the same.<\/p>\n<h2> Comparison Chart: White and Brown Eggs<\/h2>\n<table>\n<tbody>\n<thead>\n<tr>\n<th> Characteristic<\/th>\n<th> White eggs<\/th>\n<th> Brown eggs<\/th>\n<\/tr>\n<\/thead>\n<\/tbody>\n<tbody>\n<tr>\n<td> <strong>Examples of chicken breeds<\/strong><\/td>\n<td> Leghorn<\/td>\n<td> Rhode Island Red, New Hampshire, Plymouth Stone<\/td>\n<\/tr>\n<tr>\n<td> <strong>eggshell dye<\/strong><\/td>\n<td> No dyes<\/td>\n<td> Protoporphyrin IX<\/td>\n<\/tr>\n<tr>\n<td> <strong>Nutritional value<\/strong><\/td>\n<td> Same<\/td>\n<td> Same<\/td>\n<\/tr>\n<tr>\n<td> <strong>Taste<\/strong><\/td>\n<td> Depends on the feed and freshness.<\/td>\n<td> Depends on the feed and freshness.<\/td>\n<\/tr>\n<tr>\n<td> <strong>yolk color<\/strong><\/td>\n<td> It depends on the food.<\/td>\n<td> It depends on the food.<\/td>\n<\/tr>\n<tr>\n<td> <strong>Shell thickness<\/strong><\/td>\n<td> It depends mainly on the age of the chicken.<\/td>\n<td> It depends mainly on the age of the chicken.<\/td>\n<\/tr>\n<tr>\n<td> <strong>Price<\/strong><\/td>\n<td> Often lower<\/td>\n<td> Often higher (feed costs, demand)<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2> Yolk color and shell thickness \u2013 what really determines them?<\/h2>\n<p> Chickens cannot produce carotenoids on their own, so <strong>yolk color<\/strong> The color of the yolk is determined by the pigments contained in the diet, including xanthophylls from corn, green plants, and peppers. The more of these substances in the diet, the more orange the yolk becomes. Therefore, a more intense yolk color does not necessarily indicate the color of the shell or better egg quality.<\/p>\n<p> <strong>Shell thickness<\/strong> Changes with the hen&#039;s age: with age, eggs become larger, and their shells become thinner and less durable. Therefore, differences in shell hardness within a single package are not related to its color.<\/p>\n<h2> How to choose good eggs?

According to the USDA, the nutritional value of white and brown eggs does not differ significantly.<\/p>\n<p> <strong>Why do chickens lay eggs of different colors?<\/strong><\/p>\n<p> This is determined by genes. Some chicken breeds produce the brown pigment protoporphyrin IX on their eggshells, others produce the blue-green pigment biliverdin, and still others don&#039;t produce this pigment at all and lay white eggs.<\/p>\n<p> <strong>Are eggs from farm chickens always brown?<\/strong><\/p>\n<p> No. Shell color depends on the breed, not whether the chicken lives in a rural area or on a farm.

Yolk color is not related to shell color.<\/p>\n<p> <strong>Do white eggs taste different from brown eggs?<\/strong><\/p>\n<p> No. Flavor depends on the feed, freshness, and cooking method.
