Over the winter I have been eating cage free brown eggs, and now my chickens are laying again. Today I compared the eggs, 2 of the cage free, and two of mine, and mine were much more firm, significantly darker yellow in the yolk, and much more rich in flavor. The cage free eggs are claimed to be cage free from small local family farms, they're from the brand "natures yolk". They are also claimed to be veggie fed and to not use any antibiotics. My chickens are grain/veggie fed and have access to a run all day. As most backyard chickens they don't have any enhanced hormones, antibiotics, or any of that stuff. The cage free eggs were a lot more runny on the pan and the yolks broke on contact. My eggs didn't run much at all and the yolks didn't break. Mine also had a thicker shell. The yolks on the cage free were yellow, but mine were significantly darker and more golden. As far as taste, I found the taste a lot different too. The cage free had more of a really "eggy" flavor, and I feel like mine had a lot richer of a taste. What's the reason for this difference in the eggs?
