I am super excited!! I have my new eggs in the bator today. Today is day 1. They went in early this morning...since I was up with the chickens anyhow the eggs went in around 6 am. The temps and humidity are spot on thus far. I worry about my ability to maintain an even temperature. So far...when testing it and even now it has been fine...but still I worry. What is too high or too low? It hasn't a fan installed but is maintaining a temperature of in the 101 range and a humidity level of 40-42%. From all I have read here for still air, that's pretty good. Will minor fluctuations here and there kill them?? I swear I am worse than i was with my kids as babies. I must have checked these little eggs a few dozen times today (goodthing for the window on the bator!
