I like my eggs white. Brown doesn't bother me much but almost every egg I've had at home in my life has a white shell. But I do love eggs. Scrambled, over easy, omelettes, deviled eggs, One eyed jacks, french toast, Egg Mcmuffins, etc.
Generally speaking, at least here in Iowa....
You'll get white eggs from the grocery store, brown eggs from farmers markets or direct from an egg farm. It's really just the breed of chicken used. Large producers use white chickens, hence eggs are white at the grocery store.
A friend of mine actually works at a local farm and I get FREE EGGS! They are brown and delicious!
I'm not sure that's true. I've kept chooks in the past. I've had (brown and white) Leghorn, (lots of) Orpington, Dominique, Wyandotte, (jet black) Australorp, Rhode Island, Chantecler and more.
I got white, pinkish, light brown, dark brown eggs from all of them at various times, so I'm not sure breed is a factor.
It's probably more to do with the type of feed they get.
Mine got a mixture of various grains, table scraps, mice when they could catch them, bugs, grass, fallen fruit, and whatever else they scratched up from the yard.
Mice? Them's franken chickens! Have you all been sneaking their eggs into this area? Bought a dozen at the local grocery a week ago and all are like this so far.
They used to run around in a frenzy, clucking loudly when they were chasing a mouse! I had lots of mice in the grain shed and they caused a lot of damage.
The chooks loved 'em. They had no problem eating them, along with spiders, slaters, cockroaches, bullants, moths, worms, centipedes, millipedes, grasshoppers, and many more..
That may also be an indication that a piece of equipment at the processor may have been out of order - pretty sure they have automated systems that check each egg for a double yolk ("candling"), and most of those get shunted aside for other commercial use.
