So for breakfast my wife boiled a few of our eggs, and one them came out like this. It's all dark green, the white and the yoke. And it smelled terrible. This egg wasn't very old, and we haven't changed the chicken's diet. Any ideas?
Oooh! There's been threads on this before. General consensus is it is the result of a bacterial infection of the hen's reproductive tract. Which bacteria? That I don't know. Maybe search the "Emergencies and Illness" forum for "green egg whites".
