incubator fluctuations?

[fallenweeble]

so i've got TWO bators going . . .
the R-Com is holding temp GREAT - i'm pretty happy and relieved that it seems rather "idot proof."
the little giant 9200 is a different story.
i can't get it to hold a temp! it is fluctuating all over the place!
in fact, i may have already cooked the eggs that are in it. eeeek.

it was doing okay the last few days (i started it up last week) but i added some more eggs in today and BOOM - craziness! and i thought i had done the "right" thing by filling up the empty space with water-filled baggies. but switching eggs for baggies didn't seem to fool the bator . . .

any ideas, words of wisdom, condolences?

It will take several hours for the new eggs to come up to temp. If you had bags of water in there once they got warm they did what water does, holds heat, and it became a heat sink helping to regulate the temps.

Wrap the bator in a blanket. Watch the temps over several hours and see what it settles down to.

When you add more eggs the temp will fall, you need to give it hours!!...to come back up to the correct temp...patience.....
