Jim, I just used it one time. It is an addictive process. If I hatched eggs every time I got the urge, my yard would not be useable... not to mention the words my husband would have for me!!! Oh, you can get free Styrofoam boxes from pet stores and pharmacies. Or you could build one from a sheet of construction Styrofoam insulation... So many options, so many eggs to hatch... such a small coop!
Since there are a few folks who have built a bator responding, how bout a bit of Q and A?
What kind of thermostat?
Any modifications? where did you place it in relation to the heat source and the fan?
What did you use for heat source? Bulbs? 1 or 2? Wattage? Did you have to make any modifications in wattage or bulb location? Bulbs above, below eggs or to the side?
How high did you run your humidity?
Hatch success? How many eggs set, how many quitters/infertile? If eggs failed, do you have an approximate idea what age, and any idea why?
Any problems, recommendations, changes that you would make for the next bator you build, or modifications to the existing one?
