These eggs are so much better than store bought because these chickens are true free-range birds. They eat grains, corn, and whatever else they can scavage, including worms and bugs. There's no such thing as a true vegeterian free-range chicken like they claim on the brown egg containers in the supermarket.
You know it's a good egg when the yolk is practically orange! True free-range eggs are much higher in beta carotene and omega-3 than their grocery store counterparts.
I trusted Peter Reinhart's The Bread Baker's Apprentice with this liquid gold and used his recipes for challa bread and poor-man's brioche. These recipes call for 4 and 5 eggs, respectively. The recipes are more or less the same: flour, yeast, water, and eggs. But brioche is richer due to the addition of butter.
