It is day 19 and no piping and no movement. I thought I saw movement before. I don't want to be hasty and call it dead. Should I candle it in water to see if there is movement? What day should I see piping? This egg was the only egg that was solid black with an air sack at day 15. The other three died early and two not fertile. This egg is my only hope If the egg rolled around a little because the incubator was tilted a little, would that kill the chick? Temp fluctuations kill the chick? In the morning it would be 98 deg F and the afternoon would be 101 deg F. How long should I wait before giving up? During lock down, can you open up the incubator to add water? Any advise would be appreciated.
