I know what you are talking about. I totally suck at this I dont think its the hova-bator I think its just me. I have ordered eggs 3 times and at this moment I have 3 eggs in bator who were due to hatch on the 7th and still dont have anything. So I took a accurite and calbrated it and it was 15% lower then actual humidity. When I put it in the other one already in there read the same humidity, meaning humidity was to high the whole time. At times when it read 65% it was actually 80%. I probally drowned my little chickies. How long do you guys think I should wait, before tossing everything out?
