i have no clue i would say not just to be safe water is a good drink for ducks (probably safest too.)
You don't...they get water and duck food.
the girl dogs do but it's not the kind of milk that we think of.
They will eat the grass themselves. Pour the milk in a bowl. Ducklings need other food as well or they will die. Go to a local feed store and buy duck starter.
you get breast milk mostly when you are reagent because it is very usual to feed your baby your milk when it comes out but before Any of that the Doctor will tell you what kind of milk you should give your baby so it does not get ill.
I'm sure you can feed your reborn baby real milk, but i would prefer a fake milk bottle.
To feed their baby.
