Egg candleing question

[Clap p 1]

I set eggs 5 days ago. Most have the typical spider or clear. I have some showing almost solid, like a day 18 of so egg. The mass moves a little like it's liquid. Could this be a "bad egg" that needs to be removed? I usually leave eggs in , even ones not developing, until day 14 of so, just in case. I've never had one explode before and don't want to start now.
Thank you for your support in my hatching endeavors.

Do you have any pictures of it?

Is it a dark shell that could possibly just be difficult to see clearly?

Light blue. Others of the same shade are easy to see through

Have you seen clear distinct veins? Was it moving?

No veins , nothing but t he picture. Not normal for a 5 day embryo.

Due to it being so dark/different from the others, I would be cautious and simply take it out. I'd open it up and see what is actually in there, because even if it's nothing serious and the chick could develop, it could somehow have complications. Please open it and show us pictures if you decide to!! I'm very, very interested about this. One of my blue/green egg layers has calcium problems, with lots of deposits on or even inside the egg shell, so if it's a trend among blue/green laying breeds, maybe it's one giant calcium deposit.

Are the eggs from your own chickens?
