Sorry, I JUST saw this post! So sorry!
I use my own duck eggs fresh out of their pen, washed off mostly, and I use a Genesis Hovabator 1588. Temps pretty steady at 99.50100.0 Humidity about 35-45% until the last 3 days, then I boost it up to 65-70%.I use an auto turner from day 0-25. I take them out on day 26 in the am, and either put upright in an egg carton or lay down on their sides.
I try not to help any hatch, but have been known to have a very soft heart and not be able to leave them alone. I only had 1 die last summer because it was a gimpy, lame duckling. (Lame duck?)
It was caught funny in the egg and once I helped it, I think it was too late to correct the bad leg. I tried, but it didn't make it. Other than that, I just have dumb luck I guess. Very fertile determined eggs and chicks too.
