Free-Range Eggs vs Store bought Eggs

Disclaimer: I'm new here.

I've read a bunch of stuff claiming that free range eggs are healthier than strorebought eggs. Does anyone have some scientific data I could see to back that up. It sounds nice. The color difference obviously exists. But I would like to see the stats.

I would focus on fatty acid profile when is comes to health. A fuzz factor that messes things up is how free-range is defined. USDA definition is not what I go by when describing my egg and meat products. Free-range for me has bird getting the majority of nutritional intake from forages, sufficient enough that the birds need little more than an incomplete scratch for energy and possibly mineral supplementation.
