I had a set of eggs hatch out Sunday night and Monday. Three questionable eggs didn't hatch. Wendesday I pulled the chicks and put them in the brooder. Because of a heavy work load, I got lazy and didn't pull the eggs and turn the bator off. I did turn it down and turn the fan off. I just looked at it and was going to clean it for the next go around. Unplugged it and opened it to find the 3 eggs zippping. So now i am waiting on these eggs to hatch so I can start the next set. Checking the temp and humidity these chicks should be dead. Temp 88* and humidity 43%. I guess i will wait a little longer to turn the bator down next time. Any other time these eggs would have gone to the feed bin. Just I have been having a fertility problem, so I thought these might have been duds. Also I might start candling a little better too.
