Lately we have been getting eggs that are mostly white-ish with a skin-tone color. Almost a very faint pink at times. When we first got our hens they laid dark brown eggs with rich orange yolks. Now the eggs are more white and the yolks are more yellow. We feed them Purina layena crumbles and cabbage from our garden on a regular basis. Has anybody else had this problem? The eggs taste fine, I just miss the nice dark brown eggs on our shelves. Also, we have NO leghorns or roosters. Our layers are 2 golden comets, 1 RIR, 1 Dominicker, 1 Australorp, 1 Buff Orpington, and 1 White Brahma.
