I set some eggs in the incubtor yesterday. Found out my themometer was off by 10 degrees which explains why nothing made it last time. So, the temp is fixed and holding steady around 99.4 or so. Occasionally dips to about 98.7, ususally when I am adjusting humidity. My humidity jumps. I get it up to 55 (right now it is at 60) and it will be ok, but in a few hours it drops to 30-35. I have tried the sponges, I am using the resvoir. Problem is, I work. So if it drops 4 hours after I put the water in the bator in the morning, no one can get here to do anything about it for a few hours. Help please, I want this batch to work. And yes, I calibrated the humidity meter I got at walmart, just as the board suggested.
