So far 5 out. But total disaster just happened! The sensor got pooped on, making it register super low 95.5 and kept pumping out heat and my other 2 thermometers were reading 112!! So I had no choice but to open it and clean off the poop and then it registered 105. The humidity of course dropped to 50% so I poured cold water into the channels through the vent holes. Then not 10 minutes later a chick is asleep on the sensor and it reads 101.5 and the other gauges are reading 96! Wow. I had to open again! (at least humidity crazy high by then at 80%) and put the dang sensor up by taping the excess to the lid. Why didn't I do this before?! Are they wrecked? There's 30 left, many with external pips. This crazy temp fluctuations were over the course of a half hour. I'm glued to the thing so I can't believe this would happen.
I don't know what to tell you, but that I hope that they make it for you.
