I set my eggs last night in the incubator, (11 eggs). I have 3 thermometers in there. 1 that came with the incubator, 1 that came with the egg turner and 1 that I bought at WalMart (a digital thermometer and hygrometer). 1 regular one is on the left side of the incubator and reads around 100 all the time. This one is placed between 2 eggs, closer to the bottom of the eggs. The second regular one is placed on top of the eggs on the right side of the incubator and reads much higher, around 104-106. The digital is placed DIRECTLY above the second regular one, also towards the top of the eggs and reads much lower than the other two at around 97. How do I know which to trust???? And also, when should I be able to candle and see some sort of sign of life/growth? I don't have high hopes for these eggs with the shipping/packaging and the amount of yolk on the surviving eggs and would like to be able to remove duds as soon as possible. I understand that if there is bacteria in them it can spread to the others and kill them???
