My kids and I found 2 duck eggs at the park day before yesterday. I brought them home and put them in the Hovabator forced air incubator that evening. It was already going with chicken eggs on Day 10. Has anyone every done this with success? I'm not going to raise the humidity much more than I've been keeping it (50%). Do you think it will work? I'll candle in a few more days to see if there's growth.
