Sorry to backup an old thread. but I was doing a search on temperature fluctuation in the incubators and found back this thread.

and I doesn't want people to have bad sense of what's going on.

Doesn't make sense at all.

Not because something is smaller that it will be warmer.

It's temperature will change faster (for same material) but it won't get warmer.
If you keep giving the same heat, it will get to the same temperature eventually.

Problem you have is either : probe placement make fluctuation in your incubator
Thermometer is not accurate (I had that problem with cheap thermometer, it would say 88.7, then jump to 91.2 in a matter of second, a good laser thermometer and another digital one proved that one to be incorect).

Try to give it some air and make the air move. Also get a good proportional tstat.


What you need to understand : heat element give you energy (not heat or temperature), the egg tubs receive it and stock it when temperature around is higher, and give it back when air temperature around is colder. Everything try to be in balance.
