For some reason one of my Jersey Giants laid a white-shelled egg. Previously all the eggs have been a shade of brown with one gal laying a pinkish colored egg. 2 days ago, my 16 gals laid 13 eggs and one was white. Yesterday all were the normal shade and I'm wondering what I'll get today. Yes, these year-old hens are hatchery stock so I don't expect perfect eggs, but the white one surprised me. All hens are acting normal, and the egg itself was perfectly normal-nice strong shell, tough inner membrane, and a beautiful yellow yolk. I was simply surprised to get a white egg after all the brown eggs. The diet has not changed: Purina laying pellets, some scratch feed, and daily fresh greens, and bread as a treat.
