1, does duck poop smell ALOT?
Well, when I got the first two ducks and put them in a large plastic tote with shavings on the bottom, yeah, their poopies smelled badly.

When I was able to move them into the sunroom, which they shared with the chickens, pine shavings on the floor, it wasn't so bad. When I moved them into the duck house, no smells. I use sand in the duck house. Easy to clean up the mess.
2, can ducks live without a swimming area?
Um, yes? When my duckies were tiny babies, I put a small plastic container in the big plastic container they were in. Those little guys loved to step into the water and stay. So I added a second container, they would rotate between the two containers.
When I moved them to the sunroom, I put a larger plastic container in there. As they grew, so did the container, until they had my largest roasting pan in there. They LOVED to "bathe" in the water!
When Walmart finally got their summer pool inventory, I bought the duckies a 5' hard plastic pool. They loved it!
I thought as they aged and as the weather got really COLD, the duckies would age out of the water pool thing. So far, nope. They even break a thin layer of ice to get into the pool when temps are below/at freezing.
When the ice was too thick for them to break, they used the water dish to wade in. I have one duck that insists on clean feet at all times!
I have heard/read that many ducks don't care for water pools as they age. Some breeds don't care at all. (People were sharing their personal experiences & that of others they knew.)
My ducks prefer one source of water for drinking and a second source of water for grooming.
Sooo.....I would suggest that you can provide something for them to get their feet wet. Walmart does offer smaller pools.
3, do ducks eat alot?
Lol - define a lot!

Our neighbor described baby ducks as "PIGS!" It seemed like they were always hungry! Now that they are in the duck house and free range, I don't think they eat a lot. They forage, even in freezing weather. I find that when the duckies get up in the morning, they are STARVING! And they like to eat right before bed. Overall, I would say the duckies eat about 1 cup each of fermented feed per day. If I don't let the duckies out soon enough in the morning, they will eat their own eggs, shell and all. Again, in the mornings, they are starving! With the cold weather, I put out fermented feed three times a day. Between the duckies and the chickens, the bowls are clean pretty quickly.
If you leave dry food out all the time, you will go through a lot more food than if you put out fermented feed.
4, I know it depends on breed, but just how loud can a duck be?
When they are babies, they are very quiet. Pekins may be the loudest breed. Campbells are pretty quiet. My ducks usually talk when they want me to know something. Or when we are just talking. Yes, I talk to all of my animals. And yes, they sometimes appear to be having a conversation with me.
4, what was your first experience with ducks like?
I loved it! I originally bought ducks for the dining room table. For eating. I fell in love with them almost immediately! To me, the ducks have very distinct personalities. They laugh, they play, they think, and they are fun to have around.
Yeah, the whole stinky poo was icky in the beginning, but that lessoned as I got better at managing their spaces. When I first got the duckies, they were in a plastic container (no lid) that was divided in half with chicks on the other side. Once they were moved to the sunroom, much easier to clean their space.
My ducks were trainable too. I trained them to walk from the sunroom, through the living room, to the outside, to their clubhouse, and back. When they moved into the duck house, I had to train them to go to the duck house before sunset.
As adorable and cuddly looking as my duckies are, they don't like to be picked up.
5, what treats do they like?
My duckies scarf down fresh fruit, fresh veggies, scrambled eggs, applesauce, oats, rice, chili mac, and pickles. Ok, not so much the pickles, but they did eat them up when thrown from the deck to the ground. Oh and they loved picking and eating fresh tomatoes and peppers. Yes, they picked their own and ate them. I have a garden area that the animals have access to. They help themselves. Oh, and bananas. Lol - they inhale banana pieces. I only offered it once. They can and do eat meat.
6, do ducks like affection?
From a distance! My ducks don't like to be picked up and cuddled. They never did. But they respond to eye contact, smiles, greetings, "I love you", and their names.
My duckies like to play games too. Not fetch or anything like that. They do silly things and we goof off together.
What else?
