this is my home made incubator that i just made. it measures L 27'' X W 20'' X H 15'' have not tested it yet still need a thermometer and humidity meter cant remember off hand what they are called lol. it has two 30 watt bulbs that in theory one will bring the temp up to a certain temp (85 to 90 degrees) then the second one is connected to a water heater thermostat to hold the heat at the proper temp. then the fan above the bulbs is to keep the heat in the box because heat rises so this is just my thoughts and theory. then it has the egg turner to turn eggs 180 degrees. it will hold 3 dozen eggs it still needs some work but let me know what you all think so far. this is my first post on the site. and im looking forward to learning a lot from this site i got my first chickens the other day and found so much info from this site alone its the best here thanks for all the info everybody.
