How long do magpie duck eggs take to hatch?

[proudduckowner22]

Hey everyone. I am wondering how long do magpie duck eggs take to hatch. From what I see on different websites they aren’t really adding up. Some say just 20 days, and others are saying about the same as other ducks. And help would be appreciated!

They should take the same time as any other mallard-breed duck, 28 days.

My Magpie's eggs started hatching right on time.
