I had a minor heart attack this morning when I went to check the incubator. I plugged in two brooder lights last night for some shipped chicks that had arrived and checked throughout the afternoon for changes but everything was steady. I went down this morning and the temp down there had gone up by at least 5 degree! I checked the incubator fast and it was still steady at 99.5. I really love my incubator... Funny enough though, humidity is going up with no explanation. Best I can figure is that adding the chicks, their waterers and heat increased the humidity in the room and it is affecting the incubator. Still just at 45% but it had dropped to 40% and I haven't added any water.
