I am learning heaps from this hatch let me tell you!!! My temps have been swinging from 98.8 to 101.7 frequently and I found if I played around with the thermostat - the temp swings were more frequent. So I let it sit and for the last 2 days the swing has been 99.1 to 100.7 and my eggs have continued to develop brilliantly and that is dispite a 3 hour power outage on day 8! So I am concluding that eggs are A LOT more resiliant that what I give them credit for! I have a forced air bator, and I dont have a wiggler temp taker, so I am resigned to the fact that the air temp can be rather variable and the actual egg temp will be far more steady. As long as the average temp is 100 then i am happy. Very excited to hear people are currently in or coming into lockdown - cant wait to see some hatching pics!!!
