I could see the possibility of that theory LG. We never had any white egg layers when I was little, and after that, white eggs were just about all that we could find in the store. Now the store is full if different kinds of brown eggs, and only 2-3 different white egg cartons to pick from.
But now we have all these hybrids that they never had back in the day. Like mom, she didn't know if they were even a breed, just "little red hens" or "stripey ones"... We've got so many choices anymore it's overwhelming! And now we throw in some green eggs as well... I've noticed the blue green CLB eggs going for as much as $8 a dozen! All they are is pretty, not a better egg, but people will pay more for something " new and exciting "
Australorps lay a nice darker brown egg, too BTW. Not near as dark as Marans, but they're a deep reddish brown, real pretty round eggs.
