:-) The ducks have approved of your shelter, but that doesn't mean they want to stay.
Wild ducks know what their ducklings need, and in domesticating ducks, humans have done their best to imitate those conditions while tweaking breeding here and there so that the flock stays with us if we plan to use them in some fashion (pets, food, etc.).
The wild momma approves of your setup.
I think it's fine to raise domesticated duck breeds because we've altered them to the extent that they cannot survive in the wild. But I think it would be frustrating/nearly impossible to try to entice wild ducks to stay on your property if they don't want to.
I'd take their visit as a huge compliment. They like the habitat you provide. Chances are they'll be on their way pretty soon. The ducklings will be able to swim almost immediately, and they are waterproofed by their momma's oil gland under her tail until they feather out and have their own functioning oils glands.
Protect any unestablished plants you don't want them to eat or trample, and they will probably be on their way soon. And then they might come back to say hi...
Enjoy!
