My incubator is like the one below. I've noticed a lot of people have the eggs on paper towel or some other surface other than the wire. I haven't done that in the past. Is it recommended? What material is safest? I have an unrealistic fear of house fires so the papertowel so close to a heat source makes me a bit nervous but clearly you guys know what your doing so I'd love to hear what you think. We go on lock down after tonight.
