I did have several ducks, but then a few died (sob) and we gave the rest to someone who had chickens and ducks both because they were hard to take care of.
They're neat, though. Picking them up is hard, they don't want to be picked up and are hard to catch anyways. They're not pets, even if they're not food (ours just laid eggs and then ran out of lifespan to live or got given to a better home with more ducks.)
Although picking them up as ducklings may be easier. We ordered them online and picked them up at the post office, and the box was going peepitypeepitypeep with very confused boxed ducklings. (Warning: If you mail order them, they might not survive the trip so be prepared for sad when opening box. It's completely legal and the box is marked "live cargo" so it's not just thrown around like a regular box.)
We had to put heated water bottles in the coop with them during the winter, too, by the way. I recommend doing lots of research before making decisions.
