I'm checking with a couple friends to see if I can borrow one of their incubators until I can get my Hovabator ordered and shipped.
If you have some basic building skills you can make one on the cheap, and everything is pretty easy to source locally...
Lower electric hot water thermostat, about $8
Porcelain light socket, about $2
Extension cord, about $2
Incandescent light bulb or two, about $1-$2 (dollar stores still carry them, or get an appliance bulb)
Desk fan or computer fan
You can also can get a dual light bulb adapter for the socket, that way you can use say two 25-40W bulbs and if one blows you still have a backup...
Wiring is straight forward...
Here is how I did mine, with the fan and light in a metal housing, not necessary but it does offer protection and helps better regulate temps...
You can using anything from a wood box to a foam cooler to a regular cooler even a plastic tote, but obviously the better insulated the better it will regulate...
I knocked this incubator out one night just for kicks and it's become my primary incubator, it's far more reliable then the cheap commercial foam ones, I dial it in at the start of the season and it holds temp steady all year, without adjustment....
