Agree with Aloisius about the yolk color. My parents raise sheep and chickens on a farm. During the spring and summer the chickens eat almost all worms, bugs, grasshoppers. The yolks have this color to them. During the winter, the chickens eat feed and table scraps, and the yolks are not as brightly colored nor as flavorful. About them breaking down over time, that hasn't been my experience. Eggs keep a long time, and at certain times of the year my parents have far more than they can eat. Even after 6-8 weeks in the fridge, the yolks have the same texture and color.
