Yes I check calibration before Starting the incubator up. no on hygro as built into the digital temp.humidity on both, should I consider a stand alone one?
Little one that had issues at hatch is finally dry, made it through the night got strong chirping convo going on with the one in the brooder, no more pipps at start of day 23. That was previous hatch that spiked that temp. Temp fluctuations this time was usually withing +/- .02 to .05
as it's fan forced I have it set to 99.5
These are eggs out of my own flock transported them about 5 miles from farm to house, and still let them sit 24 hours , had a broody hatch out 11 and only lost 1 after hatch last week she did have some quitters and 2 that died on shell without pipping, but think most of those can be contributed to she had to many eggs but wouldn't let us take any, all the girls helped her and she tossed 6 out finally out of 30
Well, that all sounds fine, but all units are susceptible to having bad built-in hygrometers, so its worth a shot to try a new separate one. I have 3 in mine, they all read differently, but I know which ones are low and which ones are high.
Oh, ventilation is another consideration. Are you keeping all the vents open? I leave mine open all the time, and never plug a vent. Others plug early, then remove. But ventilation for hatching is critical.
