Ever See a Fertilized Slug?

Hey guys, I've got something interesting to share. A few days ago I had this clutch laid. The female is a yellow belly that had a retained egg surgically removed last year. She recovered quickly and the vet gave her the okay to breed this season. There are some spots on a few of the eggs that look like the typical under-calcified areas of a boob egg, and one egg that looks entirely like a slug, but has blood vessels.

My guess is that this is a side effect from the surgery. Possibly scarring or whatever. Perhaps a vet or someone with more medical knowledge and experience can comment on that. I don't think the "slug" egg will survive, especially if I leave it as is. There's already a foul smell coming from it. I posted a video of the clutch on my YouTube page and have had some suggestions on what I might be able to do to help the egg. Does anyone here have any suggestions or input? Thanks in advance!

First off,I don't see a "slug". It's good that they are already separated,so when mold starts you can get them out easily.

I know it's not a slug. I choose that title to grab attention. :)

However, it does look similar to a slug. I thought it was one until I noticed the blood vessels. I've heard from someone that has a similar looking egg currently healthy at 30 days. This one is still looking good. But yes, being separated will make disposal easier if it does die.
