All right, I am going to be incubating my first eggs-mallard eggs in a little over a week now. I have been researching the subject and I have a Hovabator with an automatic turner coming, but from what I have read, hand turning is a better method, at least with the hovabator. I am wondering why hatch rate seems to be better for hand turning. I have a hypothesis that I would like to throw around, but keep in mind, I am completely new to this so I might be way off. I have read of a 10-15 minute cooling period, which I think I am not going to do, followed by spritzing, can be helpful with waterfowl. I am hypothesizing that the reason why hand turning duck eggs may produce better results is not that eggs should be on their side, but because when you open the bator to turn, you are cooling the eggs down a bit, which might be very beneficial. With an automatic turner, you don't have to open it and the eggs don't get cooled. Anyone have any insight to my hypothesis? Are there any good falsifying experiments? Anyone interested enough to try to test it?
