Many years ago, when I lived in south Texas, I had a flock of free-range hens of a mutt variety. There were Australorps, Leghorns, Rhode Island Reds, and some Barred Rocks, and young uns mixed breed. The hens all laid eggs with rich, wonderful orange yolks. When I sold/gave away my flock and moved from the area, I tried raising chickens again, but no matter what I did, I could never get those rich, golden yolks. My original flock lived on a diet of bugs, regular scratch feed, and whatever they found in the scrub brush/cactus land. I never added beta carotene, carrots, or marigold flowers to their diet, they did it all on their own. How can I get those beautiful delicious golden yolks back?
