The orange yolks you see on the left of the pan are from pasture-raised chickens. The eggs with yellow yolks are from chickens that live in a building and are commonly available at the grocery store.
The difference in color is due to the difference in diet between these two types of chickens, with living green plants available only to chickens living on pasture.
All pasture-raised foods, including milk, chicken, turkey, beef, lamb, and pork, are nutritionally superior to foods raised in a feedlot or a building.

A note about this data – We don’t think saturated fat and cholesterol are bad; these constituents, like proteins and fatty acids, appear to be in every animal, pastured or not. These tables are presented to show that the levels of these constituents vary depending on how the animal is raised.
Pasture-raised is best.
“The profiles of omega-3s, saturated fat, cholesterol, calories, vitamin E and vitamin A are all better in grass-fed products because of what grass contains. Grass contains a whole host of macro and micro-nutrients. When an animal eats those components, they’re subsequently present in their foods. It’s not possible for grain-fed animals to get all those components. The other big thing is ruminants – cows and sheep – have digestive systems that are set up for foraging, and not for eating grains. When they eat grain they get sick more easily and require antibiotics. The diet can be supplemented, but it’s well known that you don’t absorb nutrients as well when they’re synthetic versus when you get them through food. The American Cancer Society advocates whole foods because of this.”
