Research says that the nutritional value is not significantly different between organic and backyard.
However, I expect the fact the backyard eggs are fresh laid is the big differentiator. The supply chain between farm and supermarket is huge, whilst backyard eggs can be laid that day.
In the US farmers have 28 days to get eggs in cartons.
Once in cartoons eggs must be sold in 30 days. Store eggs can be quite old. Freshness is likely a big part of flavor. I suspect that the US egg washing method may affect flavor as well. Home eggs typically aren't washed and are only a few days old. The eggs I sell were laid that week.
Free Range is not the same as organic - if you compare backyard eggs to eggs that are basically someone else’s backyard it’s understandable there’s little difference.
Free range just means the chicken can go outside or turn around. It says nothing about the feed or breed.
