What is going on with this quail egg?

I candled all my eggs today and I found this in quail egg 2, it showed up out of nowhere and looking closely it looks like tiny veins, is this egg worth keeping?

If this is one of the eggs from your other post, I'd put an X in pencil on it and check it again in a week. It might be fine.

This is not a egg from my other post. This egg has been in the incubator for a couple of days now and this has just showed.

I don't check eggs until Day 7, 14, then prior to lockdown. Many times I skip the middle one. I don't like to open the incubator any more than I have to.
