I recently caught a female allegator lizard in my backyard and named it Alexa. after about 4 days it layed 7 eggs in my aquarium. I found them the next mourning and started researching care for them. I placed them in a Tupperware container with very fine moist soil and buried them about a 1/4 of the way into the soil. Sadly shortly after ants got into Alexa's aquarium and killed her. Making me want at least one egg to survive even more. That was a month ago and I'm expecting them to hatch about 3 or 4 weeks from now. I recently noticed however that some eggs started getting dimples in them. I found out it was a moisture problem and sure enough when I added more water the eggs plumped right back up. But now the egg that had the worst dimple is getting a slight yellow to the bottom of it and the bottom only. Is it mold or a failing egg? Should I try wiping it off? Is there something I should do to the soil in the container? The inside of the egg looks fine. I candle it a lot to see if the state of the inside changes and it doesn't. I'm fine if it ends up failing. I just want to know how I can prevent it if it happens to my other eggs. I'd love to hear anything that you think would be helpful! Thanks!
