The carotenoids that cause deeper yolk coloring are xanthophylls, which are more readily absorbed in the yolks. (Lutein is one such xanthophyll, and a lot of lutein means a lot more orange.)
Xanthophylls are found in dark leafy greens like spinach, kale, and collards, as well as in zucchini, broccoli, and brussels sprouts.
Omega-3 fatty acids are highly concentrated in oily fish (especially cold-water fish like salmon, tuna, and mackerel), shellfish, algae, tofu, and high-fat plant foods (like brusssels sprouts, navy beans, and avocados).
Did you know that chickens are not meant to be vegetarian, no matter what your premium carton of organic/grain-fed/cage-free eggs tells you?
Chickens are omnivores by nature and their healthiest diets include meats, such as mealworms, beetles, grasshoppers, grubs, and whatever creepy-crawly they can pull out of the ground. I’ve even heard of chickens attacking and feeding on small rodents and snakes!
