Egg Candling: Will the spot move?

[freezefamilyfarm]

Today is day 3, so it is kind of early to tell and I'm not discarding any yet, even the one I saw nothing and think is not fertile. In some I saw a small spot and it seemed to move or swim even after I held the egg still for a few seconds. Is that normal? These are green and light brown eggs. I will check again at day 5 or 6. I have one big egg that is a duck or a goose egg (not sure, got it from a neighbor) it had a large spot that looked more like some of the candling photos I've seen for day 5 or so. Any input is appreciated!

I was afraid it was just the motion of moving the egg, but it still did it after waiting a few seconds, so WHEW!!!! at least I know some of them are fertile and alive.

Here's a thread I started that chronicles the progress of a batch of eggs that I incubated this year. There are some candling photos that may be of interest to you.
