I've read that as the chick grows to fill the egg that they put off heat. I'm noticing just this past couple of days that my incubator is running hotter. I'm on day 16 and the chicks are really starting to fill up the eggs. My temps have been stable at 100-101 degrees until the last 24 hours or so, It's going up as high as 103.7 I'm concerned to say the least. My bator is a still air Miss Prissy style. Is the developing chick creating this additional heat? I'm afraid to turn the temp back because I'm not sure what's happening here. I've been pulling corks to try to get some of the heat out, but then the humidity takes a nosedive. I certainly don't want to cook my babies! Any help?
