When I did mine I just ran them under the faucet for a second or two. Then set them on the counter till I remembered to put them back in the incubator.
I'm not advocating that. Just pointing out you're much more attentive than I was. Can't wait to see what hatches for you.
Well.., our “winter” isn’t much around here — low temps around 50F and frost is a newsworthy event.
Housing the klings may be tricky for a couple of weeks; they’ll end up in the living room until I can’t stand it, then garage. With the timing I’m thinking either fresh duck eggs or roast duck by the end of summer. 
Wait, how good was the hatch that way? Maybe you’re on to something. I only left mine out for five-ish minutes.When I did mine I just ran them under the faucet for a second or two. Then set them on the counter till I remembered to put them back in the incubator.
100% hatch rate! That's not counting yolkers but 7 eggs developed and 7 ducklings hatched. Honestly I was counting on a few not making it or I wouldn't let my kids set so many eggs. We still have 1 male and 1 female. They are khaki campbell crosses.
Dont give up I am rooting for the hatch!!
Still four lively embryos. Nobirdy lagging developmentally, so I’m daring to hope just a little bit — even starting to speculate on breed. They’re too well developed to be muscovies (darn!), so they’re some sort of standard. Pekins are my guess, since roast duck is also an extremely popular item at the deli there. Just 9 more days and we’ll see!How’s it going @Xouie?
