Need advice for non-hatching eggs!

[keyt1969]

I set 20-some chicken and duck eggs of various breeds. They were due yesterday and 7 of them hatched Thursday. The others weren't pipping or anything so I candled them and all but 2 were moving really well. Problem is there's no sign of pipping or anything. What should I do and how long should I wait?

Leave them alone. I don't mean to sound abrupt, but back away from the hatcher. Nose to the glass is ok, because that is what I am doing right now ( except for when I am typing)LOL! I know that ducks take longer than chickens, like 28 days I think, and sometimes eggs develope at different rates depending on where they sat in the incubator, humidity, and air flow, or lack there of.
