It takes while before you can see anything, both because of rate of development and needing experience to see what is there at each stage.Ok I've been candleing every day from day two could that be the no movement issue?
Why I posted my first experience above to maybe guide you, if you read it thoroughly.
Do some googling and find some videos and/or images of what a developing egg looks like at certain days of incubation.
Tho a lot of the candling images are done on small white eggs, the larger and darker the egg, the harder it will be to see in there.
The most important tip I have for candling is to use a very bright light in a very dark room.
Makes a huge difference in how well you will be able to see.
I use a windowless room that's close to the incubator...or wait until late at night.
