To check if an egg is alive, use the candling method. Hold the egg in front of a bright light source in a dark room. Rotate the egg slowly; you should see the embryo moving if it's alive. Alternatively, place the egg in a bowl of water; if it sinks and lays flat, it's fresh, whereas a floating egg may indicate it's no longer viable.
