Duck and Chicken at same time?

[Kangasox]

I'm certain this has been answered, but I can't find it searching past posts. I have incubated ducks lots of times with great success. Was thinking about incubating some chickens this year as well, and I know about the differences in humidity needs and incubation length...but can they be successfully incubated together, just setting the duck eggs a week earlier?

Yes, the duck eggs would need to be set a week earlier for them to all hatch at the all time.
I'd probably just keep the humidity at an average of 40% or so, and you shouldn't have any issues. Watch air cells of course though.

Make sure you brood them separately after hatching.
