Been watching this thread but haven't posted on it yet. Anyway my incubators run year around. Just hatched a group of Khaki Campbell's on Tuesday and a group of bantam Cochins a week ago Friday (went 61 for 62). Also I have Barred Rocks, Easter Eggers, Australorps and Rhode Island Reds hatching next Wednesday and then we have Barred Rock/Light Brahma's hatching on Wednesday that are from our egg layer pen. All are laid in my breeding pens. Oh, I can't forget about the Silkies that are hatching on the 2nd!
Anyway, had a heart stopper yesterday with one of my cabinet incubators. All my cabinets and hatchers run incubator warehouse digital t-stats and I've had very good luck with them. When I walked by the cabinet, I noticed one of my good thermeters was reading 104.5. So I looked at the other 2 and same thing. The t-stat was saying 99.5 so I grabbed the thermal gun and hit a few eggs, 104.5'ish. Dang it. Luckily I had an open hatcher that was running and was able to move them. These are the mixed pen eggs hatching Wednesday. It couldn't have been that way more than a few hours and looks like they'll be fine. I did go ahead and candle this morning and they are alive. The most I've ever had to offset one of t-stats is .4 degrees to match calibrated thermometers and I have 8 of the t-stats. After trouble shooting this, it automatically offset itself -5.0 degrees. Wow!!!! The keypad was locked and I have no idea what happened or why it happened. I reset it it and it's been steady according to the log. I think I'll just order a new one for the piece of mind.
Wow, glad that you caught that! Guessing the eggs in there are past 7 days or there about?
