Glad the thread is useful to everyone in the new year!

If you have a bright enough light and light enough shells, you should be able to see something inside the eggs. However, lack of light, thick shells, dark shells, and you won't see anything unless you crack open the egg. But if you did that... you'd not have a chick later. If you can't see anything, wait to candle on day 10 or 14 from the fat (air cell) side of the egg.
