There are a variety of products that have proven successful as incubator mediums, that is, the substance that the eggs rest directly in as they develop. When choosing a medium, there are a handful of factors that must be considered. You need something that will retain water and maintain humidity within the egg container, something sterile (or close to it) and something that will not promote excessive growth of molds or fungi. Most breeders and hobbyists turn to either perlite, vermiculite, or a combination of the two as their medium of choice. Both have proven highly successful, and render high hatch rates. Both of these substances are examples of naturally occurring siliceous rock. When heated to a proper temperature, they expand to many times their original volume, producing a very light, absorbent material that naturally resists molding.
