My husband has always been a white egg eater. Myself, I grew up on brown. We were always under the impression that brown eggs were better for you. More nutritious. And you could tell by the darker yolk. Was any of this true? Nope. When I first started with chickens, I chose by breed, not by egg colour, but, all of my birds laid brown eggs of different shades, save for one easter egger that laid greed eggs. And guess what? They all taste the same! People were weary of me putting the green egg in the carton when I sold them. But I'm not one to pick through my eggs for people. I've got plenty of customers to sell to. I promised them that once they cracked the egg open, they wouldn't be able to tell them apart.
Here are 3 eggs. One white, one brown, one green. Inside, they're all the same.
When it comes to farm-fresh eggs, all the birds are fed the same feed, thus, all the eggs taste the same, no matter the colour on the outside. If you chose to separate your birds into separate pens and feed them differently, then, the eggs would taste differently and the yolks may differ in colour.
Inside, most eggs are white. Which means that's the colour they start out as. The pigment is added to the outsider later.
The breed of the hen will determine the size and colour on the outside, what they eat will determine the inside!
This year I actually got several white egg layers to prove to my husband they're all the same, but he's still not convinced. And maybe you won't be either. Maybe telling you that brown eggs actually start out white and the colour is added later, will help? So brown eggs stay in a little bit longer to add the pigment. Which is why you may see white eggs cost less in the grocery stores. And if you look inside of an eggshell after it's cracked, you'll notice they're all white inside? (Save for some coloured eggs, which are the same colour both inside and out, but this still does not effect taste or yolk colour)
Which one is which? You can't tell!
I know everyone has preferences, mine my only preference is that they're fresh! (And preferably my own!)
