Alright, so I've been patient, incubator has been up and running and fiddled with for 3 days. I think it's time. I have 41 eggs rounded up, as I realize the hatch rate might not be the greatest first time around, or then again, I might get surprised. They are eggs from my girls. So, refresh my brain. 99.5 degrees F (37.5 degrees C ) , for model with the fan, right? it's at 37.8 right now, so just turned it a hair to bring it down. humidity, this is what I get confused with, right now it's sitting at 47 % If I put the eggs in today, day 19 would be ......... ??
