I put a bunch of eggs in my refrigerator and later put them in my incubator. I read that you could store eggs in a fridge but with the eggs already in incubate, I put a thermometer in my fridge and the temp was 38 degrees. Is this too cold for eggs? I had them in there for about 5 days at the most, some were less. I have no candling light so maybe y'all know a free/easy way to candle eggs. Thanks much!
