I agree with Delisha. I check for internal pipping if they did not hatch on time.
Also, I know this sounds weird BUT.... You can hold the egg up to your ear and listen to hear for a popping noise. This is the chick breathing/pecking inside the air cell. Just hold the big end up to your ear. I candle to check for internal pipping then hold up to my ear to make sure the egg is alive.
