I am running a custom made incubator with 72 egg capacity. I need to check on it about every 6 hours when weather changes. Only every 12 hours when weather stable. A 22 egg Nurture Right 360 needs to be checked just daily.Had a second week candling session this morning. I think there were maybe 4 that weren’t fertile out of maybe 50 eggs. Glad I did it, one egg was cracked. Stopped that bomb from going off. I set up a new incubator yesterday and it’s holding temp and humidity really well. I’ll set a couple hundred eggs in it this morning.
My early season hatch rate poor, 40 to 60%. Too much exposure to low temperatures prior to egg collection. Later cohorts doing much better.
