Hi I've made a home made incubator which is working really well so far. It's made from styrofoam and currently at the bottom, there is the turning tray sitting. Eggs will go on lock down soon and I need to remove the tray and put something under the eggs.. I have seen so many people are using these wire mesh at the bottom which would be great but i'm really struggling to find an affordable piece ( i only need a really tiny piece for the bottom). Lowest i've seen is $15 for a few sheets and that's as small as it gets. Does anyone know of any alternatives I can find at a general store or at home? thanks!
