Hi everyone - I am new here. I dont breed ducks, rather I live adjacent to the Hudson River and am concerned that someone dumped some backyard ducks in the river. I am in NJ and mainly there are just mallard ducks and canadian geese. But about a month ago I saw four ducks that just didnt look like they were native species. I caught one - what we believe is a Swedish Blue (in the second pic) - and brought it to the Wild Bird Fund in NYC who will be finding a good home in a sanctuary for him. There are three light beige ones left that do not look like mallards that I am concerned may be backyard ducks and would not survive the winter. Please let me know any thoughts you have - the closest I came was a Yellow Swedish. But maybe it is wild and is perfectly suited outdoors. Thank you for your responses. Tiffanie
