Broody hen hatching duck eggs

[Birdmama2020]

Hi, I have a broody hen and a duck that didnt want to look after her eggs. So I gave some eggs to my hen and she has been great. They will be ready to hatch any day now.
This is my first time hatching eggs and even more so with them being hatched by my hen.
Is there anything I should be prepared for or should be doing?
Should I seperate my broody hen from the other girls? (I don't have any roosters.)
Should I remove the ducklings from my hen? Will see take to them?
Any advice is greatly appreciated

I have had many chicken hens raise ducklings. Upon occasion I have had flock mates that would attack the ducklings. I would separate the hen and ducklings from the flock if they were mine.
