My incubator is full as of this morning and I am going to fire up the old helix as a spare. I am really wondering what is the safe temperature range for eggs. What is the lowest and highest temps people have incubated eggs out at? I try to keep them at exactly 89 but I know they must have a pretty good range of temps that they can be at for long periods of time before they go bad. I am not wondering about short term spikes or drops in temps more of what temps could they survive at for 12-24 hours. If I have to guess I would say 85-91 but does anyone know for sure?
