I'm on my 3 rd hatch with a Hovabator 1602n with a fan. I have a hygrometer/thermometer that i keep inside. My first two hatches I did good. 1st Hatch last year: I set 12 eggs. Only 11 where fertile. All 11 hatched healthy. Ended up with 8 hens and 3 roos. Ran temps a little high between 99.5 and 100 F. humdity between 45-50 % 2nd Hatch( 1st for this year ( a new rooster over 39 hens) set 18 eggs only 8 were fertile, all 8 hatched healthy, ran temps the same as 1st hatch. So far it seems like I have 4 hens and 4 roos. They are only 7 weeks old. This is my 3rd setting. I set 36 eggs and I am trying to run my temps at 99 to 99.5 F this time around. Humdity 45-50 again. So I just set my eggs at noon for the Easter Hatch Along. Right now, I have it so my thermostat shuts off at 99 and the lowest the temp gets while its bringing the incubator back up to temperature is 98.4 . Is this okay or should I adjust the temperature a little higher? I now see the appeal of paying more for a digital. But I've been happy with my hatches so far. Thank you.
