Two circles inside Chameleon egg?

I was only able to capture the one circle on my camera, it looks like two dense circles inside the egg, across from each other. What could this be?

I've moved the eggs multiple times (changing out the bin) and the eggs have been bumped twice due to my stupidity of egg bin placement..

The eggs will be 5 months old the beginning of November.

Also noticed a lot of eggs have lines in them. A few have small pieces of the outer shell knocked off.

They look okay ? , did they hatch ?
