i made my incubater out of a small refridge, its about 18 inches square. i put a little giant egg turner in it, 2 light sockets with 15 watt bulbs, a light dimmer switch, a thermometer with a temp reader probe going to the inside, a water pan and 3 sponges, a small electric fan also hooked to a dimmer switch, a funnel and tube to add water without opening, a 6x8 inch glass cut in the front, 6 holes to release humidity if needed with plugs . we are now waiting for our hydrometer from ebay that has a wireless inside probe. if anyone is interested my wife will help me post pictures. my first incubater was made out of nice plywood but it molded really fast.
