Hi everyone, today is day 10 for my duck eggs so I'm going to be candling them later. I was just wondering how long is safe to keep the eggs out for? I thought the best way would be to lift the whole tray out and then put the lid back on the incubator to get the humidity and temp back up, whilst candling the eggs in the tray out of the bator? I'm just worried that it may take some time to candle all 22 eggs, take pics and draw the air cell size on each one. Any advice please?
