How about giving those eggs 21 days? Sometimes, rarely, not often there are late hatchings.
Do you know what you would look for if you candled the eggs? If you don’t, look at this: http://archive.is/pS5DK Chicken eggs but eggs “is” eggs.
There is another way to look for bad eggs if you don’t candle. When you look at them and if they’re old enough, you’ll see a clear line of demarcation about half way between one end and the other with one end being darker. That’s a bad egg.
