My son ate our first two pullet eggs this morning. I was thrilled to see that they had bright orange yolks. I have two friends with chickens. The friend whose chickens free-range have those same orange yolks. The other friend, whose chickens are kept in a run, gets yolks that look more like grocery store eggs. My chickens are in their run the majority of the time, but they get to free-range an average of 1.5 hours/day. I get "premium" food for my girls (I read and compared ingredient labels before buying). Is it the chicken food, the free-ranging, or the garden scraps that make my hens yolks so dark? I wonder if they'll get pale over the winter? Is there any correlation between yolk color and nutrient content?
