turn the bator down to about 90, they will be ok in there till morning. make sure you get a couple heat lights when you go. if you have to give them water just try to do it fast they will be ok for a few.
I was using a desk lamp for a temp setup and it started smoking and stopped working even with a new bulb. I found a heating pad. Another trip to tractor supply I hope they have one they didnt have a water thing today.
