Help with hatching Magpie Ducks

[Ms Delyla Quack]

I am not a 'new duck owner' anymore....but I am new at hatching them!!!

I have 15 fertilized Magpie duck eggs in our incubator. (without a turning device....I am it!!!)
I have had them in an egg carton type holder for most of their incubating period. Heat 99.5 and humidity at approx. 50 degrees

I am wondering a number of things (I see different ideas everywhere and I am getting confused)

-When should lay them down to hatch (the first egg's 28 day incubation period is in 7 days)
-When do I need to turn up the humidity and turn down the heat?
-Will this effect the other eggs that are not due yet?
-Can I let the ducklings hatch in the incubator with the other eggs?

Thank you

This sticky applies to waterfowl, as far as I know.

And we do have some hatchers. You can check out the Thread Formerly Known as Hatch Day is Today - it is not active, but you can see who is familiar with hatching.

I will definitely do that.
