It's hard to picture, as a real human who grew up eating eggs and not laying them. Since the human race has always faced the threat of starvation, I expect the cultural norm would have developed a long time ago that eating your own eggs is perfectly natural and normal. A taboo against eating them would be a serious disadvantage during a famine. We would grow up with many cultural influences about the eggs. Religious texts like the bible would no doubt make moral pronouncements many people would follow without question. It might even be a political issue.
