Is it possible to work out what day chicken eggs are on though candling?

One of my silkie is sitting on two eggs and I’ve lost track of what day they are on since I did not think they would make it this far. You can see them moving and there is quite a large blacked out area in it. Is there a chart I could follow maybe that could give me a rough idea.
Thank you

I candled them again and looked at the pictures and now I’m doubting if they are actually alive and if I saw them move or imagined it

Yeah. I’ll candle again before I put them to bed and send some photos then

Hiii so I candled them again and there is movement but what is stressing me out is the two eggs look a quite different stages and I don’t know why.

Egg one

Egg two
Egg two looks a lot fuller and darker
