Check out Etsy. You'll probably find a lot of them there. My brother collects them. He has collected them over time. When he is traveling if he finds one in his price range he adds to the collection. He lives in a city house, nothing woodsy about the location.

I have an older family friend that used to duck hunt in his younger years and collected amazing antique duck decoys. He has them displayed on shelves in his office. I would try antiques stores or larger antique fairs.

Funny how we go through stages of what catches our eye and have to have. Last year, I went to a vintage shop event that they hold every year. I walked by one vendor and was smitten with his decoy ducks and ended up getting quite the bargain. $35.00 for all three ducks. My grandson was recently admiring them, so one may go to him. Try scouring vintage markets, tag sale, antique shops.

I have a small one with my accidental bird collection on our breakfast room hutch.

Found it at a local antique mall — a couple of booths always have some.

I just went to offerup.com to search and there are literally dozens and dozens of duck decoys for sale in a 25 mile radius of me in Los Angeles. I thought I would turn up one or two!

I love duck decoys. The ones I have are from Etsy I believe. Wish I had more. I’m going to try Charish as the previous person suggested. I keep what I have on the mantel of the kitchen fireplace.
