Well I finally had my first hatch. I set 42 chicken eggs and hatched 30 chicks. I had 10 eggs that apparently weren't fertilized as there was no embryo development at all. I'm not sure about two of the eggs. I think I'm going to candle all 53 of the batch of eggs I put in yesterday, which brings up a question. Would keeping the eggs out of the incubator long enough to candle all 53 at once take too long? Or should I candle them in small batches, say 20 at a time? You guys were right when you said this was addicting!
