I was looking into raising ducks

Have you checked your local Craigslist, city Facebook yardsale page, ads at feed stores, etc, to see if many people in your area sell ducks? I'm guessing you mean meat ducks, right? I know around here, there's a pretty good demand for duck eggs, but not so much for meat ducks. Some people sell Muscovies for meat, but I'll see their ads on Craigslist for forever, trying to get rid of the same few ducks.
