Really, nothing. Yes, you read that right! NOTHING!
Brown eggs are laid by red chickens and white eggs are laid by white chickens.
Brown eggs have more omega-3 fatty acids, but the amount is tiny.
Chickens that lay white eggs are more cost efficient.
They are smaller than their brown colored counterparts, so cost less to feed.
The type of feed may affect the egg’s nutritional content as well as the color of it’s yolk.
