I'm working on making a "styrofoam cooler" incubator. I really want it to be forced air, because I made an incubator years ago that wasn't and only got 2 hatched out of 36 eggs (although we did have a power outage early on, it was November, and the eggs were shipped to me, so that all may have had something to do with it.) So I have 3 different PC fans that I salvaged from an old tower. Connected one to a cell phone charger as shown in an instructable I found, and nothing. Do you think that I might have either 1. wired it wrong or 2. used the wrong type of charger? My second question is, using a 60 watt bulb, is it imperative that I use a thermostat, or can I get by without one? I might be able to get one for free but that involves asking someone who I don't really want to ask. Third question, I only have one hen whose eggs I'm collecting, where/how should I store the eggs while I wait until I have them all? I'm hoping to be able to collect and hatch (or try to) 6 eggs. Four, how do I know if the eggs are fertile? Do I just assume they are until the embryos are old enough to be seen during candling?
