What substrate do you have them in and what are your temps and humidity?
I've successfully hatched a couple eggs actually that grew some slight mold on them. They were so far along and I had the extra space in my incubator I decided why not try and see what happened.
That being said, I've also had moldy eggs that clearly went bad and the development ceased.
I'd separate any that have mold on them so they dont spread to other eggs.
I use vermiculite and the temperature is around 83,85 degrees and humidity is around 75%. So I should just separate them? I heard I can use a fungal cream and it will help. They are 30 days from hatching (expected hatching). Thank you so much for your help!
Yes separating them should be fine. It should at least help keep the other eggs from developing mold, especially if the moldy eggs are kept in a tub with a lid or something.
I have no experience with fungal cremes so I couldn't give any advice on that. Honestly mold wasnt much of an issue for me when I was breeding so there's probably others here who can offer you better advice on the matter.
