We also have "pet" ducks.

Fred & Ethel have been hanging around our house for a couple of years now. I still have no idea how they found our house I am really not a bird person. But one day there they were, at our front door, so I fed them! (yes, BTW, I feed any animal that comes to our house/yard) They usually come for breakfast and then again at dinner time.......HOW do they know when I feed the kitties dinner is still beyond me

Most times they spend the whole day in our backyard, I guess its safe from the neighborhood kids. I feed them right on our patio, so the boys can watch their every move. They have even come up to the screen door and almost have touch noses with the cats. They all get along........as long as there is a screen door between them
