Brown eggs vs. white eggs.

The primary difference between brown and white eggs is the breed of the hen, not the nutritional value, taste, or quality. White-feathered hens with white earlobes typically lay white eggs, while red or brown-feathered hens with red earlobes lay brown eggs. Brown eggs may be more expensive due to the hens being larger and eating more feed. 

Here are the key differences based on this Times of India article, this Eggoz post, and this Reddit thread:

• Nutritional Value: There is no significant nutritional difference between brown and white eggs. Both contain similar amounts of protein, vitamins, and minerals.
• Taste: The taste is not determined by shell color, but rather by the hen's diet and freshness.
• Cost: Brown eggs can sometimes be more expensive because the hens that lay them are generally larger and consume more feed, notes Times of India.
• Shell Thickness: Brown eggshells may be slightly thicker, but this does not affect the interior quality, say Lohmann Breeders.
• Pigment: Brown eggs have a pigment called protoporphyrin IX, which is absent in white eggs, explains Eggoz. 

Ultimately, the choice between brown and white eggs is a matter of personal preference and availability in your area, says this Times of India article.
