I am incubating iguana eggs, and everywhere I look I can't find an exact humidity that I should be using. I have a hova bator with the temp set to 84`F, and I've tried the humidity at 80`. I am using super hatch as the medium. I started out using tap water, but switched to distilled since I kept having mold issues. I've tried letting the humidity down and it just makes the eggs cave it. I've lost a lot of eggs, and this happened before with my leopard gecko eggs as well. I know they're fertile, I have both genders of iguana. Is there anything I can do to make sure they don't mold, but still get the humidity they need? And what should be the humidity level? I do have home for the babies, if any of my eggs hatch.
