So, I had the bright idea to buy a used double oven for my kitchen. Turns out, it didnt work when I got it home and wired it up. So I was left with this monstrocity. We had been using 3 Little Giant incubators and had filled them to capacity. I had seen folks using refrigerators before to make incubators, so I thought I would give this a go... BEST thing I have ever done. My hatches have gone as high as 96% in this thing! It was so simple to do. I just used a paddle bit to drill a few holes in the sides (that could later be plugged with a cork if needed). I got a bottle lamp kit from Wal-Mart (6.88), and a small desk fan (4.88). I ran the light and fan cords through one of the holes I had cut. I had to play with the proper wattage of bulb, but found that a simple 60 watt bulb keeps the temp perfect. And the fan, placed below the light bulb, circulates the air so that the temp is stable throughout the incubator. I have a large cookie sheet of sponges that sits in the bottom that I fill with water as needed for humidity. I already had two spare turning racks laying around that sit on the oven racks. I ran those cords through one of the holes as well. The top portion holds my two turners, and the bottom portion was done in the same manner to use as a hatcher. When eggs are ready to go to the hatcher, I just remove them from the turners and place them in a plastic tray that is lined with some of the rubbery cabinet liner. As I said, great hatches. It is not the prettiest thing in the world but does suprisingly well for a used $30 oven and a few small purcases from Wal-Mart.
