I found this egg among my groceries (see photo). It has a strongly ridged shell with the pattern of ridges resembling veins or arteries, while the surface between the ridges is densely pitted with a few isolated, tiny, pimple-like protrusions. The deformities are more prominent on the narrower end of the egg. What is the explanation, and is such an egg safe or palatable to eat? I did not feel inclined to put this to the test.
