I buy eggs from my parents, who have free-range chickens: beautiful Buff Orpingtons.
The best eggs in the world are farm-fresh from chickens that have eaten a natural, varied diet. Especially when the weather is warm and they're eating green things and insects, the eggs have so much flavor.
Two of my kids had never eaten an entire fried egg in their lives. They thought they were yucky. The first time they tried the free-range eggs with dark yellow yolks, they loved them and cleaned their plates. Fresh eggs also fry and poach much more neatly, so they look nicer, too.
