I had a hatching party last night as well. I was concerned about this. iI unplugged the wrong bator 10 daysago for 10 hrs or so. I did have 4 ew quit , but locked down a bunch. They started were supposed to hatch friday, and My one line of wellies are always earl. so I waited an extra day to lock down. 1 wellie pipe in my hand as I moved them from bator to hacther. That was kinda a funny feeling. But My Line 1 wellies all hatched out friday afternoon and last night, except the early piped on. He was out friday morning. Th other line of wellies have 2 out right now and the other pipped, I have 1 project blue barnevelder out, and cant see if the other one is pipped. I have 5 or 6 black coppers out and can't see how many blue and blue splash coppers out, It is a moving mess in that tray. I can see a couple are piped and couple zipping. Now if my easter hatch goes , I will be happy . That bator has an electronic controller on it and did not like the storm the other day. It was kinda like stuck and flcikering. The temp was up to 113, but the egg temp therm was correct. I did candle a few and found no clears and they were deveopling right on schedule, so hope I did not fry to many of them. I shut the controloer off, turned it back on and its working fine.
