I try to "dry" incubate them. I keep little water in the incubator, but I spray the eggs with water 3 times a day. This brings the humidity up to around 60% but then it slowly drops. At lock down I increase the amount of water in the incubator to stabilize the humidity. Still working on the best humidity for lock down. If it is too high they drowned if its to low they shrink wrap. My guess is around 50%-60%. This is what has worked for me in the past.
