Can a chicken raise a duck?

So, can a chicken raise a duckling?.... Well, let's say, they had to get to know each other.
The chicken in this video is the same one that also helped us with incubating Albert's friends. She is so sweet and I felt sorry for her that she had no chicks to raise for herself.

Text in this video:

We only have chickens and no rooster
so our hen was sitting on empty eggs
She was so dedicated and really wanted to be a mum
So I got her a present
She could see it, smell it: This was not a chicken egg
A few days later I checked the egg
right on schedule
so a couple of weeks later, on a beautiful morning...
to make sure all would go well, I kept the egg with me during hatching
it was strong it was healthy all should go well
so when it was dark outside, I snuck the duckling under the hen
The next morning...
Now listen to that sound and watch the little grain
In 'Chicken" this means: "Look, I've got something nice for you"
Little chickens will come running when they hear this
the hen kept calling him
but the duckling went for a swim
"Hey, water is dangerous, get back here"
The hen wanted to understand this weird chick
so she started to study how it was trying to eat
She thought his leg looked like a nice little worm
But that's alright...
The duckling thought he could eat his mum too
ouch!
the little one needed to eat
so I showed them the duckling food
