Chicken eggs are only fertile if they have been fertilized. The kind that people generally buy in supermarkets or grocery stores, in order to eat them, are infertile and contain no embryo. Eggs can only be fertile if the hens that lay them are around roosters, and nearly all eggs sold in stores are produced in factory farms where the hens are restricted and never see a rooster. Any that potentially would have a rooster in the flock will be specifically labeled. Even eggs labeled "free-range" are not going to be fertile if there are no roosters in the flock.
