I have a trio of Anconas. I love them. They are a lot of fun to watch, and they round out the yard well.
They get the bigger pesty bugs my chickens don't try to tackle, and make quick work of Japanese Beetles and, I have heard, hornworms.
They are "messier" than chickens.
They get things wet, but I switched their enclosed run to a hardware cloth floor with a 2" layer of pea gravel & it made it less soggy.
I find it less gross than the chicken coop, which is always so dry (a good thing) that when I churn the litter...
... but people always talk about the fact that they are messier. Their water buckets & pools are something to see. Twice a day I pour this thick, brown goo out of the bottom of their bucket & rinse it to give them clean water. It is FUNKY, and I wash that every other morning or so. Their pools I clean the sludge out once a week (a little less in winter as I don't leave water in it overnight), but I power spray them before I fill them everyday. I moved the duck house over to our least productive garden & am letting their water drain into it this winter, and raking the hay out & covering the beds & garlic with it. (My lemon balm is still growing over there.)
There is a lot of water transport involved. I think that is the BIGGEST consideration I would make if you do not have a pond, stream, etc.
I carry A LOT of water from the house to the duck house now that it is winter. I find it an enjoyable part of the routine, but I also plan to add some rain barrels to my setup expansion project this spring.
I would read "Storey's Guide to Raising Ducks", try to visit different types of ducks.
Also, be really realistic about what you can handle for noise level, and what you want from the birds before you get them. I LOVE runners, and they are great layers, but after meeting a few I realized my plans were not a good fit for runners (yet) & I needed something with a little less enthusiasm.
I got Anconas because they are good layers, meaty enough, and great foragers. I also LOVE them. I think they are very pretty, and I think that counts for something.
They are much less affectionate than my chickens. They were friendlier when they were little, but they are all hormones right now. I am fine with that. I like them as ducks, they can be whatever kind of "pet" they want.
the chickens free range and so did the ducks... and they got along fine. The chickens loved to go in the duck house and eat their food and play in their hay
The chickens DEFINITELY run the yard here. My four laying hens "free range" in the duck house more than anywhere else in the whole yard. The ducks wouldn't DARE set foot in the chicken coop. Lately my teenage hens are trying to stand up for themselves. Until a chicken looks at her, she rethinks her attitude awful quick once a hen gives her the eye. They bully the cat, and he is not a little kitty. They all free range together most of the time & are more & more like a flock, but I house them separately also.
superchemicalgirl your ducklings are so cute. Did you hatch them yourself?
