Ok i am soo terribly frustrated!! Both of my themometers say something different!! I dont know which one to believe! I dont want to kill my chicks! They are both Acu-Rite themometers. One has been outside for a while, and the other one we bought yesterday because it has a hygrometer (humidity thingy). one (the old one), says lower all the time. The other one (new w/ hygrometer) says higher. I dont know which one to believe!! Has anyone had experience with either/or one of these? How can i know which one is right? Here are pics of them, still argueing about the temp. In this pic, the temp is very close. But they have been as much as 5 degrees different before.
