I want to make a cabinet-style incubator. A friend was giving me some lumber. I thought he said it was plywood, but it turns out that it's 1/4" paneling. Would this be okay to use for the cabinet? I can get some foam sheeting for insulation, I figured I'd need that anyway. I'm also planning to use a ceramic heat emitter, are these a fire hazard like the heat light bulbs? The plan is to make this thing big enough to hold several eggs but small enough so I can use my hovabator turners. These are 19" x 19", so the outside dimensions (depth and width) would be 21". What's a good height to have between each rack? I'll have other racks (at least 1 but probably 2) in addition to the 2 with auto turners, one for hand-turning and one for hatching. I don't know what else to ask, any suggestions would be helpful.
