I really appreciate that excellent advice Adam.
This egg was RANK!
So...I went through the process that Adam described...although I don't have a sink in my reptile room. I took the group of three out and put them in another tub to work. Well first I wanted to see if I could separate them with VERY careful peeling of the eggs apart.
Luckily, one egg broke free fairly easily...with a bit of force, and with my stomach wrenched with nervousness.
The other egg...well, that wasn't seeming to separate as easily. So I cut the egg open, and I really didn't know what to expect it to look like...it looked mostly like a hard boiled egg, and there was a tiny maybe quarter inch long "worm" attached to the mass... The yolk was obviously rotten, but there was an embryo inside.
Once I emptied the eggs contents...I trimmed the egg shell back a bit...and figured...I'd give peeling a go again...well I must've gotten a tiny bit of yolk on other egg...but maybe it acted as a lubricant...I don't know really, but the remainder of the bad egg shell came free.
The area where the egg was attached on the good egg looks thin, but isn't torn at all, and looks good overall. If need be I may add "New Skin" to that part of the egg shell.
After I re-setup the two good eggs I dusted them with the anti-fungal powder like suggested. Hopefully, that's all they'll need and those eggs are out of harms way.
Thanks again for the advice.
I was going to take photos of the bad egg's contents...but it was too ripe to keep it in my house any longer.
