I have a comparison . There are two eggs from different sources. the brown shell is from our big black chick, Sparkle. The white shell is from the store. See how the egg whites from the brown egg keeps its shape, while the one from the store spreads out. The brown egg also tastes richer.
Here we see two eggs. The one on the left is from our big yellow chick, Dandaleen. The one on the right is from our big black chick, Sparkle.
