This morning I was repiling the leaves in the chicken run to make a large mound for the chickens to scratch through. I discovered an egg in the leaves, buried about 4 inches deep. It was a white egg, so I know that hen has only been laying for 2 weeks. Our daytime temps are around 60F and nights dropping into low 40F's. After washing the egg off, the white shell is stained brown from the leaves. Other than the discoloration of the shell, the egg is in good shape, but I don't know how old it is. Is this egg safe to eat or is it closer to a balut at this point? OK, I know it's not a fertilized egg, so not technically a balut. But is it safe to eat or should I hard boil this egg and feed it back to the chickens? What is the best method to do with a found egg and the age is uncertain?
