Hatching duck eggs

[girls and guineas]

How long does it take for pekin, and magpie/mallard duck eggs to hatch?? I have a magpie hen sitting--and a pekin that has been on and off for a couple of days. I hope the eggs are good--since the duck hens didn't sit all the time at first??
Anything else I need to know?? First time hatching out duck eggs!

I'm new to this too, but I think it looks like 24-27 days seems to be the norm. The sticky thread is FULL of helpful advice I just read up on!
