Does anyone still have the manual for the Kebonnix 12 egg incubator? My last 4 hatches have been terrible with most of the surviving eggs being shrink wrapped and needing assistance. I put a different thermometer inside and temp was off 5 degrees also

. I think my kebonnix is failing. Which sucks because it's only a year and half old .
If you have the manual can you tell me the recommended humidity for day 1-18 and then for lock down? I've always done 50 or so the first 18 days then around 70 for lockdown. But maybe I am remembering wrong. Thank you!!
