This is an easy to make egg incubator that doesn't cost much.

Supplies

You are going to need these supplies to build the incubator.

Cooler
Plexiglass
Duct tape
Lamp kit
Thermostat (I used a water heater thermostat)
Dual light bulb socket adapter
Electric tape
12v DC adapter
2 computer fans
Thermometer
Chicken wire and hardware cloth
A block of wood
Sponge
Incandescent light bulbs

Step 1: Make a Window in the Top

First, you need to cut a hole in the top of the cooler. Then I used duct tape to attach a piece of plexi glass on top.

Step 2: Drill Ventilation Holes

I next drilled a few ventilation holes that can be covered with duct tape if it gets too cold.

Step 3: Wire Up the Lights and Thermostat

I cut the cord on the lamp and attached the wires to the thermostat. I set the thermostat to about 100 degrees.

Step 4: Connecting the Fans

Next I connected the two computer fans to the DC adapter. I'm using one of the holes I cut earlier to string all the wires through. Make sure you connect the wires inside the cooler. I then secured the fans nicely on either side of the cooler to provide good airflow.

Step 5: Putting It All Together

Now it's time to put it all together! Notice that I left space behind the thermostat, this is so that it can get an accurate reading. I put a piece of chicken wire under the lights so that they don't rest of the bottom of the cooler. I then put in a wet sponge to keep the humidity at the right level. Next, I cut a block of wood to support the hardware cloth. And lastly I attached the hardware cloth on top of everything. Now it's time to test if it works!

Step 6: Turning Everything On

I plugged everything in and it works great!

Step 7: Add the Eggs!

Now it's time to add the eggs! They should hatch in about 21 days!
