Dear Yahoo!:
What's the difference between white eggs and brown eggs?

Dear Lynn:
We started by searching Yahoo! for "eggs." The results were a little too general, so we revised our search phrase to "brown eggs" (with the quotation marks) and things became clearer.
One of the first results was a link to a column from Thrive Online, an Oxygen.com site devoted to women's health. The column addressed the health benefits of brown eggs versus white eggs and concluded that there is no nutritional difference. Contrary to popular belief, brown eggs aren't a healthier alternative to white eggs.
The site explains, "The color difference is due to the specific breed of hen, according to the Egg Nutrition Center. Hens with white feathers and white earlobes will lay white eggs, whereas hens with red feathers and matching-colored earlobes give us brown eggs." But were there any other differences, we wondered?
Returning to our search results, we clicked another link and visited the web site of the Rochester Hatchery in Canada. While we didn't find any pertinent information, we did enjoy the colorful illustrations of brown-egg-laying chickens, and yes, they all had reddish-brown feathers, though we couldn't vouch for their earlobes.
At Owl Kids Online, a fun science site for kids, we learned chicken eggs aren't limited to just brown or white. They also come in blue or even a nice speckled finish (though you may have to make a special request at your local supermarket for these).
After exhausting the Yahoo! search results, we jumped over to Epicurious.com for their thoughts on the matter. We searched their food dictionary and came across the egg entry. It also assured us that the color of the eggshell had nothing to do with the taste of the egg.
So, there you have it: The difference between brown eggs and white eggs is purely cosmetic; it's just a matter of a baby taking after its mom.
