I have 7 hens... 1 BR, 2 EE, 2 RIR & 2 White Leghorns. I have been told and read often that the White Leghorns will lay white eggs. All were hatched the 2nd week in March 2010. THe last 3 days, I have gotten 6 eggs that are brown or green (EE's). Has anyone had or heard of a White Leghorn laying brown eggs?
