Two things are going on with my current eggs and I am not sure what todo about it! First, I set my hatch date in my phone with an alarm....then I lost it!. I can't remember for the life of me when these were set! It must be over 14 days... but how much over...not sure. I am guessing they are 14-15 days though... Secondly, though my house has central AC and is usually between 68-74 degrees and I check the incubator often and see that it is always between 99.5 and 100.5 my thermometor has a min/max history button. I remember clearing it when I set it up and when I hit min/max the other day it said 107.5 max! I have no idea how that would have happened. I have a little giant and I really check often (and I work from home right next to it all day) and it is never far off. Could it have just gone nuts and gotten that hot? So, how do I know that these eggs of unknown age are still alive? When I candle they are mostly dark inside now with air pockets in the right spot..but I am just using a small led flashlight I have and it isn't great. I can make out only a small bit of open space at the bottom and don't see movement but can't really see well at all. I don't see any rings or that sort of thing. So, I don't know how long to give these possibly dead eggs! I have other good eggs in with them and would really prefer this doesn't end with a smelly explosion! Write your date on the eggs! So, how do I know they are living or not? And... is my incubator just too old and something is making the temp spike occasionally?
