Chickens were bred to produce white eggs over generations. So The breed of the chicken can determine the color of the egg. Some chickens Lay green eggs it doesn’t mean that they are bad. major egg producers Bleach their eggs as well. The important thing is that the eggs are free range and are not fed antibiotics and steroids. This will be printed on the carton. Free range alone is not good enough.
Also I don’t know if it’s a misprint but you infact can get organic eggs all over southern California.
