get some humidity to them, some peat moss will do, or sphagnum. just set it around them but not touching, moistened NOT soaking wet. The other eggs shouldnt bother them if they are still viable. Hopefully they will still plump up. What are the temps in the enclosure? Those need to be in the higher eighties for them to do well. if not. find a way that wont dry the eggs out more than they already are.
Find a way to get an incubator set up, i have a cooler one set up, with 2 ft of flexwatt and a thermostat. It was very simple to set up. You could also try making one out of a 10G tank, with a glass sauce jar filled with water and a fishtank water heater in that. with a plexiglass cover. ( not 100% on if this is a tried an true method, but ive heard that it works, but never tried it myself)
Incubating them artificially will be better off so you dont disturb them by taking mom away from them, or stress mom out. They definitely look like theyre in need of some serious intensive care though. (
if they will even make it, which others might elaborate on)
Once mom is off of them, and you have something set up if you are planning on them hatching out * i dunno if they will or not, but ill hold out hope for you*, you have to clean mom, AND her enclosure. EVERYTHING. even all of the accessories. you dont want it to smell like her eggs. That should help to get her back on feed ( if she hasn't eaten yet)
You say they were unexpected, is mom housed alone, or with her "partner in crime"? If she is with the male, Separate them, and wash him too. and get a second enclosure. if not, did something happen where she came in contact with a male at any point in time ( if you bought her like that unknowingly)? Im interested to know...
Be prepared to get some small setups for the babies too. Theyre going to need clean enclosures set up and running at the right temps for them, if those last two do end up hatching.
Good luck.
