BoutrosBoutrosGalusGalus: what'd you use for heating? I've heard lots of people having great success with fish-tank incubators. I wanna build one now! Ijust need a fish tank... your name is the most complex BYC pen name yet.. wow. I had to look at it four times to get it right! But anyways; what's the temperature of the room your tank is in? 70* is perfect and should be cool enough to not die of sweating and not kick your electric bill through the roof.
Try setting he room temp at 70, putting a warm towel over your incubator, and if that's not enough, add a higher wattage bulb. As long as your temps stay betwen 97-101 for the most part, you should have a decent hatch.
P.s! If is still doesn't work, don't give up!
