OK, I know you guys have answered this question 100 times and I have read pages and pages. But, I just want to be very sure. I made a chick bator (Miss Prissy style) from an old Coleman cooler with fan and water heater thermostat. I could not find a wiggler but made one with baggies/water. I have messed with it for a week now. When the WW temp is perfect the 2 other therms (one is a reptile probe type the other is an Accurite Hum/temp room one.) are 101 to 105. I am thinking my focus should be on keeping the WW temp steady and as long as that is true we should be good. Is that true???? I think I could go insane trying to get them all the same. Oh and I also have a jar of water in there for a heat sink. Thanks for the help.
