I'm incubating uromastyx eggs and will soon have some chuckie eggs. Does anyone know what the best temp is for these kinds of eggs? The Hovabator's set on 86 degrees, for lack of a better number. Also, I don't have a fancy scale or humidity gauge. Are those necessary to hatch eggs, or is there a good rule-of-thumb way to keep the right amount of water in the vermiculite? Is vermiculite a good medium in which to hatch eggs?

Thanks for any responses.
