try to keep it up but no don't worry. I just hatched 13 of 14 chicks yesterday and my temp went between 99.2 - 106. Obviously you don't want the instability so try and keep the temp where it should be. Make sure to keep the bator away from drafts and in a room with a fairly constant temp. Also when you change the temp either higher or lower make tiny adjustments not drastic ones. Good luck and hope i helped. What kind of bator were you using?
