It is similar to what happens with rare and heritage breeds. Not many have them and those that do have them, do not have a lot of them. Hatcheries have thousands of birds in breeding pens so they can supply lots of eggs.
Yeah, I prefer an egg that actually fits in the cartons too. Most of my White Leghorns eggs do but some are too big to close tightly. We have had a few redstars that regularly produced eggs too big for the carton and double yolkers. It's fun but not practical. I imagine that our birds just have been allowed to lay longer into their lives vs the commercial set ups and that is why the eggs are getting so much bigger.
