How accurate they are for hatching eggs? I have built a small incubator(for about 12 eggs) and I have purchased two Digital Oral Thermometers(different brands) the seem to be displaying the same temperature but something tells me they are reading about 1 or 2 degree Celsius higher than what should be but I can't tell until I get myself an actual Mercury one(hard to get now a days), anyone has used these on doing DIY Incubator?
