Alright, I did the Chicken egg experiment and the result as of now are: My home is 68-70 degrees F and three eggs were tested at day 10-11
3 hours out: All embryos still moving but slowed, one was returned to the incubator and returned to normal movement.
5 hours out: Embryos still moving slowly. Egg that was replaced in the incubator quickly returned to normal movement
9 hours out: The last egg was returned to the incubator. I would not have kept it out so long but I fell asleep for a while. It seems fine anyway. It has been marked egg number five and will be watched.
This result seems promising since the temperatures in my incubator were still slightly above the norm in my home, and beyond that while chicken eggs are more advanced at day 11 and therefore likely more hardy, their normal temperature is higher than that of emus by a few degrees and more importantly they cool much faster since they're so much smaller, have thinner shells, and were left outside the incubator rather than in it as I presume the incubator is at least moderately insulated. Only time will tell. Lots of time. A month to two months to be exact. I hope these emus are worth the stress they've caused me.
