No, ducks do not have the ability to transform into swans. Ducks and swans are different species of birds with distinct physical characteristics and behaviors.
There is no proof that aliens exist. If they do, it is possible that alien races could have avian characteristics (i.e. owls, ducks, hawks, etc.).

"A few." Ducks can fly......the problem tells you as much "Then some of the ducks flew away." Ducks fly South for the Winter.

of course they can, almost all ducks can fly except some of the domestic ducks.
Some day soon, I would like to visit the park to feed the ducks. I saw some ducks in my neighborhood last week. Some neighborhoods allow ducks to be kept as pets.
All ducks can fly, even domestic ones.
Well, ducks eat some insects so probably.
This depends on what kind of ducks you have. Some of the basics are quacking, swimming, mating, eating, pooping, making loud noises, and waddling around. Certain ducks are better than others at these things. I have noticed that call ducks are especially good at quacking and making noise. Runner ducks are good at running and have a unique shape that looks a bit like a wine bottle. Some ducks are good at hatching. Some are very good at flying. Some ducks are actually too heavy to fly, like Ruins.
