OK if I didn't 75$ worth of eggs from the BYC members in my incubator right now Id go to my bonfire pit and burn the dang thing-I have a hovabator 1602N with turner-temp was awesome for the last 4 days-put the rest of the eggs in last night-left it alone this am I get up and bang 104.6! what the heck! I flipped the top open blowing on my eggs to cool them down--temp went down to 100.8 in about 10 minutes-an hour later 100.0 which for a still air is still low right? the humidty has never been a problem it's at 41% and Im happy with that...why does this thing do that??? We are gone 10 hrs a day to work-and need sleep-this only does it when I go to bed-I wake up and I get a heart attack in the morning? it is day 5 for 3 eggs and day 1-3 for the rest ( it is full) do you think they'll be ok if I dont keep getting spikes? I want to incubate soo bad and have been so good not to open when I dont have too-(lesson learned from last time)-as Im looking at it now the heater light came back on-ahhh-thank you just needed to blow off steam!
