I'm on day 3 of incubation. The first 2 days went without a hitch -- the incubator held a steady temperature and humidity. I was up a few hours after I last turned the eggs and when I went to look at the temperature it said 106! Argh.... made me so mad.
I have the incubator in a little room between bathroom and linen closet, no windows, no drafts. I haven't made any changes to the room temperature. I cracked the lid a bit and adjusted the temp down on incubator thermostat -- which is way off. It still ran a bit warm, but not as bad.
What makes these darn things spike like that when nothing has changed?
I made a little bracket from thin flashing metal and have the temperature probe taped to it so that it stays at the proper height and doesn't flop around when incubator is opened. The wire between the thermostat and plastic is taped to the bracket, but does not touch the probe end or sheet of clear plastic that came attached to it.
