1. You pick brown eggs over less-nutritious white.

Result: Up to a 25% price premium paid for what is, basically, an aesthetic choice

Even in the era of fancy omega-3 eggs, brown eggs retain a certain rustic allure. But a large brown egg contains the exact same proportion of white and yolk, and the same nutrients, as a white egg. Brown eggs simply come from a different breed of hens, which are often bigger birds and require more feed than standard white-egg-laying hens. Those costs are usually passed on, adding to brown eggs’ “specialness.”

What to do: Choose by wallet or style sensibility; either way, you’ll pick a good egg.
