I had to get a new incubator in an emergency situation (shipped eggs coming in the mail and old bator blew up). I set up the new one and its holding a steady temp, I'm just not sure that the thermometer that came with it is accurate? I didn't get a second thermometer, just didn't have time to buy one and decided to trust the one that came with the new bator. I candled this morning and it should be about day 4. I usually candle at day three and always see something. These eggs have nothing going on in there. Nothing at all. If my temp has been too low all this time, is there any chance of a hatch at all?
