My 12 silkie eggs came this morning after a very rough delivery. Box damage was terrible, but no eggs were cracked, so I'm hoping for the best and have them resting right now with small ends down, outside of the incubator. They weren't supposed to be here until Friday...but gotta move on. I just got the pro series 4200 yesterday and of course in a panic today to get working right. How do you control the humidity in this thing? I've removed water from two wells, left it in the center portion and it's still showing 68 on humidity. I've even removed both plugs. Should I remove the water from the center well, which is bigger, and try with just one side well at a time? Do you guys remove both plugs?
