This is my first year owning ducks, I have 4 Anconas (3 ladies and 1 drake) i love them like crazy, i will say they are a messy animal, i didnt realize this until i actually owned them (their whole indoor area is covered with pond liner so it can be cleaned by spraying it down and shop vacuuming it during the winter months. My ducks have been with and without a pond/swimming pool, i will say they seem alot more happier when they had their swimming area, which needs to be cleaned every three days or so right now because i do not have a filter. Ducks do need something that they can at least dunk their heads in so they are able to blow out anything that gets lodged in their beaks and to clean themselves. But they are a huge part of our family now and i look forward to getting a few more in the spring and possible hatching some little ducklings.
