Differences in eggshell color
In fact, many factors cause different eggshell colors, but the most important factor is different chicken breeds. Eggs from different breeds of hens can have different colored eggshells, depending on the type of pigment produced in the hen's body.
For example, the pigment in brown eggshells is mainly due to “protoporphyrin IX” which is made from heme.

Other reasons for different eggshell colors include the age of the hen. If a hen that originally laid brown eggs gets older, the color of the eggs laid by that hen will become lighter.
In addition, the chicken's diet, living environment, and stress level can also cause the color to become darker or lighter.
Which color eggs are good for health?
Many people think that brown eggs are more nutritious than white eggs, but in fact, both types of eggs contain the same nutrients.
Scientists have even conducted related experiments to determine whether eggshell color has a different impact on the nutritional content of the egg. However, they found that eggshell color does not affect the quality or nutritional content of the egg.
Brown eggs or white eggs taste better?
Although the color of the eggshell does not affect the taste of the egg, the feed the chicken eats, the freshness of the egg, and how it is prepared can all make a difference in taste and palatability.
For example, eggs from hens fed a high-fat diet tend to taste better than eggs from hens fed a low-fat diet. Also, the longer eggs are stored, the more likely they are to lose their flavor.
Tips for choosing eggs
When choosing chicken eggs, in addition to paying attention to the size of the egg, you can apply some of the tips below.
- Look at the outside surface. You should choose eggs with thick shells, moderate size, and a hard, tanned shell. You should not choose eggs with a very smooth shell surface, because these eggs have often been stored for a long time before being sold.
- Shake the egg to listen to the sound inside. This method is very simple, we just need to put the egg to our ear and shake it. If there is no sound when shaking, it means that the yolk of the egg is still fresh. On the contrary, if you hear a sound like water hitting the inside, it means that the egg is old.
