Last season I used a plastic container and used vermiculite as substrate. This season I hope to use vermiculite with that plastic grid thing I keep seeing to keep the eggs off the substrate. I was also looking into using a different kind of egg tub. I have two 2.5 gallon glass tanks that I used to house fish in. If I were to wash these (several times) and sanitize them, would they make good egg containers for the incubator? They have glass lids that sit on top that would help keep the humidity in. I can provide a picture if one is needed.
