Varietal Eggs. I hadn't seen these in America. Free-range eggs are a big deal in England, for both humanitarian and epicurean reasons. I am skeptical of the difference according to either reason. Chickens are very stupid creatures and bred for contentment in small cages. Eggs are rather distant from everyday chicken functions, and I wonder whether eating bugs and getting exercise really affects them. But I could be wrong. My wife says free-range eggs do have a different color of yolk.
