I just hatched 8 Coturnix eggs in a used little giant with a fan, a ninth egg was still "an egg" infertile. So that makes it a 100% hatch! Little red plugs were missing so I taped over them. Probably beginners luck. I filled the water troughs daily. The temp swung from 94 to 103 the whole time, I just kept fiddling with the knob. I turned the eggs 3 to 5 times a day. Dropped them a few times, I have carpul tunnel. Listened to them for scratching noises. Added a big sponge and towels so their little feet did no get stuck in the wire at lock down, Took the tape off the holes, still fiddled with the stupid temp. What is a hydrometer? There was condensation dripping off the windows. Must have been wet enough. They all jumped out of their shells within 24 hours and were all over the place. After 2 weeks I am brooding them in a babies portable playpen. I just ordered eggs. I hope that I have the same kind of beginners luck again.
