Hahaha. What a cute invasion you got there. But sorry Ducks aren't common in the place/country I lived in, are ducks considered as a pest in your neighborhood? Or you are just making fun of them? Because I consider those ducks harmless and they might be migrating from somewhere.
nah, they aren't pests. I love ducks. They stick to their own and keep the pond looking nice. The only thing that I don't like about ducks is their brutal gang rapes that happens from time to time. I've seen a female die from this before. It's not pretty.
That being said, geese are pests. They shit everywhere, fight in my yard where my toddler plays, are loud, and just annoying.
But I do love the ducks. :)
