One of the top questions we receive here at the Egg Nutrition Center is whether the nutritional profile of an egg is influenced by the housing conditions of the hen, particularly free-range versus caged. It’s a reasonable question to ask. Free-range hens may forage for bugs and plants, which could conceivably alter the nutritional intake of the hen and hence affect the nutritional content of the egg. It has also been questioned whether certain housing systems affect stress levels of the hens that may in turn, lead to changes in the nutrient content of an egg.
