If these factors matter to you, look for clear labeling and reliable information about the farm or production system.
Why are brown eggs sometimes more expensive?
In some markets, the hens that lay brown eggs are larger and require more feed. This can increase production costs and help explain why brown eggs sometimes sell at higher prices.
Packaging, transportation, brand positioning, local consumer preferences, and the scale of production can also influence prices.
A higher price does not automatically mean better nutrition or superior taste.
What should you buy?
If brown and white eggs are both fresh, properly handled, and produced under comparable conditions, either can be a good choice.
Compare their price, size, production information, and freshness rather than paying more because of shell color alone.
8. Check the Packing Date and Storage Information
When choosing eggs, dates and storage instructions are more useful than many traditional visual tests.
Depending on the country and seller, the carton may show a packing date, best-before date, expiration date, or other traceability information. The precise labels and legal requirements vary by location.
Read the information carefully and select eggs that have been handled and stored according to the instructions.
Why does storage matter?
Egg quality gradually changes with time. The white becomes thinner, the yolk membrane weakens, and the air cell grows larger. These changes can affect how the egg behaves during cooking.
However, freshness and safety are not identical. An older egg may still be usable if it has been stored correctly, while an egg that looks fresh may still contain harmful bacteria.
Temperature control is particularly important. Refrigeration slows quality deterioration and helps limit the growth of many microorganisms.
If eggs are sold refrigerated, keep them refrigerated after purchase. Avoid leaving them in a hot vehicle or on a kitchen counter for extended periods.
Should you choose the carton with the latest date?
A later date can be a useful consideration, but it should not be your only criterion. Check that the packaging is intact, the eggs are not cracked, and the seller is following appropriate storage practices.
Once you get home, place the eggs in the refrigerator promptly and follow the storage guidance on the carton.
Keeping eggs in their original carton can help protect them from physical damage and reduce the absorption of strong odors from other foods.
9. Try the Water-Float Test at Homeβbut Know Its Limits
The water-float test is a familiar household method for estimating the age of an egg.
To perform it, gently place an intact egg in a bowl of water.
-
If it lies flat on the bottom, it is generally consistent with a relatively fresh egg.
-
If it rests on the bottom but stands more upright, it may be older.
-
If it floats, the air cell has likely enlarged considerably as the egg has aged.
As moisture and carbon dioxide gradually escape through the shell, the air cell grows. This makes an older egg more buoyant.
However, the test measures a physical change associated with age. It does not directly detect Salmonella or other pathogens.
Does a floating egg always have to be discarded?
A floating egg is likely older, but floating alone does not prove that it is contaminated. Conversely, an egg that sinks can still be unsafe.
For this reason, the water test should never replace checking storage history, inspecting the shell, and following food-safety guidance.
If an egg has been stored improperly, is beyond the recommended use period, or has other warning signs, do not rely on the float test to justify eating it.
It is also best to perform this test only when needed at home, rather than placing eggs in water before storing them. Wetting eggs can interfere with their protective surface and may increase contamination risks if they are handled or stored incorrectly afterward.
10. Look Beyond the Egg to the Conditions on the Farm
The hen's environment and diet can influence certain characteristics of an egg, including its fatty acid profile and some vitamin levels.
For example, the feed given to hens can affect the amount of omega-3 fatty acids in their eggs. Some specially formulated feeds are designed to produce eggs with higher levels of particular nutrients.
But these differences are not determined by shell color.
Are free-range eggs always more nutritious?
Not necessarily.
Free-range, pasture-raised, organic, and conventional production systems refer to different farming practices. Their exact definitions and requirements depend on local regulations and certification standards.
Some production systems may offer advantages related to animal welfare or outdoor access, but nutritional differences vary with feed composition, breed, season, and management.
An egg from an outdoor-raised hen is not automatically more nutritious than every egg from a hen raised indoors.
If you prefer eggs from a particular farming system, look for credible certification, clear labeling, and transparent information about the producer.
What about eggs from village chickens?
Eggs from small farms or village chickens may differ in shell color, size, yolk appearance, and flavor. The hens' diet and access to outdoor environments can contribute to these differences.
Nevertheless, the term "native egg" or "farm egg" is not, by itself, a guarantee of better nutrition or safety.
The most important questions are whether the hens are healthy, whether eggs are collected and handled hygienically, and whether the product has been stored correctly.
Buying directly from a trusted producer may help you learn more about these practices, but trust should be supported by transparent handling and storage procedures.
11. Why Do Some Egg Yolks Look Darker Than Others?
When you crack an egg, you may notice that one yolk is pale yellow while another is deep orange.
Many people assume that a darker yolk always means a healthier egg. In reality, yolk color is influenced largely by the pigments in the hen's feed.
Ingredients such as corn, grass, and certain plants can contribute pigments called carotenoids, which affect yolk color. Feed composition can therefore make a yolk appear more yellow or orange.
Is a darker yolk more nutritious?
Not necessarily.
A deeper color may indicate differences in the hen's diet, but it is not a universal measure of protein quality, freshness, or overall nutritional value.
Some nutrients, including certain carotenoids, can vary with the diet. However, a dark orange yolk does not automatically contain more of every beneficial nutrient than a pale yellow yolk.
The appearance of the yolk can also be influenced by breed, production conditions, and feed formulation.
What should a normal yolk look like?
A normal egg yolk can range from pale yellow to deep orange. The yolk should generally have an intact membrane when the egg is first cracked, although this membrane becomes more fragile as the egg ages.
