I was wondering more about dry incubation methods. I started of last year with two bad hatches of ducks as I read high humidity was important(75%) and the the air cells never grew big resulting in the death of all of my babies. That was the end of my effort last year as it was way to discouraging. After doing a lot more research, I came to the conclusion that the humidity was to high and decided to plunge in again this year with some Khaki Cambells. I have 18 right now doing really well, or it seems, but I still think the humidity was a little to high, even though I was keeping it down to 45-55 and the air cells were just not growing. I decided to take all water out of the bator and run it like that for a week to see if that would change anything. Today is day 16 as well. I really need some sound advice. When I candled them last night it did look like a couple of the eggs had bigger air cells and that was good, but I am not sure I am doing the right thing. Also, should I mist if the air cells are not big enough yet??? Thank you!
