Answer 1

U.S. consumers have become accustomed to factory farm eggs, the yolks of which are usually quite pale. It is true that hens raised with good access to pasture generally have deeper colored yolks. There are also additions to feed that farmers can use to heighten color. Here is a decent article on the topic.
