Yep, Geese make poops as big as my Cody, I wouldn't let them use my entire yard, I would fence off a large area for them, IF I would get them. I also love little ducks, years ago when I lived on Long Island for Easter my neighbor's husband got her 3 little ducks, she let them splash around in her bath tub
it was the guest bathroom lol, in the summer she got a little kiddie pool, by this time they were grown, beautiful white friendly ducks. It was so cute and relaxing watching them jump in and out of that pool. I like Geese cause they are fresh lol, are like watch dogs, but I won't get any, there are to many predators that kill fowl where I live.
