For my 4-H project, I would like to make my own incubator. I can't hatch anything out of it because of my parents, but I think it would be very cool to enter into the county 4-H Fair. Here's the picture that I found and I REALLY like the design. I figure I'll need: Thermometer and Hygrometer Tinfoil Hardware Cloth Water Dish Plexiglass Plywood 75 Watt Light bulb with a Dimmer I don't think I'm going to put a fan in or an auto turner because it's more of a hobby than commercial. I've read that the humidity should be kept at 50-55% and the temperature should be kept around 100 degrees Fahrenheit. I've also read that lock down is on day 19 out of 21 and is when you do not turn the eggs 3 times a day anymore. Is this correct? What else should I add to it or is it good enough.? What else do you think I should know?
