Sheesh Kelsey I have about 3 months before I even consider touching the AC in these parts. NewChickMom, I know exactly what you mean about finding room with the turner in there. I have several of the Walmart digital thermometers and it is still going to be tight. I don't plan on hatching all 42 eggs so I removed a tray or two for the room. Unless you are doing a dry incubation method the 'normal' humidity should be between 50-60% so you are right in the norm. Is the plug in or out? Mine is out right now and it is still holding humidity well. I think I read on here where folks are putting aquarium tubing in the plug hole and using a large syringe to inject water in the tubing to refill the tray so they don't have to lift the lid off. I think I may try that.
