Eggs aren't fertilized (no roosters :|). If you really want to get down to the ugly truth of eggs, you're essentially eating chicken menstruation...And there's no ethical problems when it's in a backyard or the chickens are free ranging. I agree that commercial poultry operations are gruesome and psychotic but that's what happens when you build these things out at scale and it's largely a result of the great-depression and the new deal machinations to end hunger. Good intentions pave the path into hell.
