Do birds eggs have to be fertilized to make chicks?
No, not all chicken eggs are fertilized. Most mass-produced eggs from battery farm operations are not fertilized, as the hens live their whole lives without seeing a rooster. Roosters must mate with the female chickens in order for the hens to produce fertilized eggs. No rooster, no fertilization. Hens are able to produce fertilized eggs for 1-2 weeks from one conjugal encounter with a rooster, but it takes a few days for the rooster's sperm to begin fertilizing her eggs.
