You can make an incubator out of a cooler very inexpensively. Here is one I made. It works great. If you don 't have a turner you can turn by hand. When I turned mine by hand I turned them approximately every 8 hours 7am, 3pm and 11pm. I put an X on one side of the egg and a 0 on the other side. Originally I had one incandescent bulb but it burned out once during incubation so I modified it and put two incandescent 15 watt bulbs in as the heat source. Originally I used a dimmer switch to adjust the heat but later put in a wafer thermostat and a fan that blows lightly across the bulbs to circulate the heat. It works great.
