I’ve done quite a lot of testing and comparing eggs.... especially with yolk colors. I also keep a lot of individuals of one breed, so I can really monitor which egg comes from which hen. Not all of them but at least 10-15 of the eggs I know right where they came from.
I’m just going to go through a few things I’ve found and thought about.
In general it’s freshness that makes eggs taste “better”. Fresh eggs taste a little better than store eggs. In many cases that may be the only thing that can set your eggs apart if you aren’t free ranging. As many have pointed out, it’s free ranging that will give you the absolute largest differences in taste and color.
Without free ranging, many times the nutrition of a backyard flock is actually LESS than commercial chickens.

I hate to burst bubbles.... but when you can buy feed in bulk, it’s straight up fresher than anything a backyard producer can get their hands on, across the board. In fact many commercial farms or larger farms are actually milling the feed. Feed efficiency is a science and a huge part of profits, and it’s a well known fact that feed quality degrades rapidly. Those bags of feed we can get at the feed store have been sitting in multiple warehouses on the way to us. But now that I’m. Using in bulk, if I’m early to pickup, theyre grinding my feed right then.
so, feed additives....
You can supplement certain things into the diet, but you do need to be cautious that you don’t offset the balance of required nutrition elements. But, some things can make eggs taste a little bit richer, I have found. The best thing I’ve found is basil. It really darkens the yolks and I personally believe there’s a pleasant change to the flavor of the egg.
anything that you do add, will take 10-12 days to become noticeable in the eggs.
One of the easiest and best things you can do is a bale of alfalfa hay if you can’t do any free ranging. Just buy a bale and put it in the run. It’s a long lasting boredom buster too.
greens are only a part of the mix and the real missing piece without free ranging is bugs. I tried growing mealworms so I could free feed them without having to watch the protein ratios of dried and I haaaaaated it. I don’t know how many chickens you’ve got but two ways to drastically increase bugs safely for confined chickens is a Black Soldier Fly larvae setup or easier is just keeping a compost pile and bringing bits of fresh compost into the run.
