That's what she claims, we'll see what mom says at a later date.
I owned 6-7 Mallards and a Swan Goose when I was a kid. Just wait until she has to empty the poop filled pool every day. (and where do you empty all that messy water?) Then they get old and fly off if the wings aren't clipped. They are cute and irresistible when they are little like that, though. I am sure she is enjoying them. I loved my ducks, and I didn't mind taking care of the pool, but it was a horrible mess to deal with in a small yard. We had to hose off the back stoop and back door because they would go up on the concrete steps.
Oh, then there was the rat problem because the rats figured out we had duck food in the garage (not cute little mice, huge rats from the field across the street). My brothers and Dad got a lot of BB-gun practice that year. Old Benjamin Pump.
