I have 2 incubator and I'm having a pretty hard time keeping the temperature stable. I have 9 hen eggs in lockdown right now after setting 36 eggs and the temp went up to 40C/104F so there were a lot of early deaths. This was in my Hovabator still air bator which is the first time ive used it. The 9 eggs are in my small bator now, a really old brinsea octagon forced air. But I candled them today since 2 should have hatched by now and the others should be hatching today or tomorrow but i cant see movement in any of them and a few of them still have a lot of light orange fluid in them. I candled them 2 days ago and 2 were ready to internally pip but theres no movement today When i first put the eggs in this bator for lockdown the temp was right then it dropped down and i had to turn it up but it went up to 39C and was still going up so i turned it down again and its sitting at 34-35C and i dont know what to do I now have 10 runner eggs (1 hatching next week, 9 in 3 1/2 weeks) and 24 hen eggs in my still air and the temperatures all over the place but i think i might have settled it at 38C now but when i open it to candle the temp drops and dosnt come back up so i have to adjust the knob again. Could someone help me on keeping the temp stable and whether you think these eggs are going to hatch especially the ones in lockdown ? thank you for any help!
