Black bellied whistling ducks

My wife and I have had a family of whistling ducks show up in our backyard, two parents and 10 hatchlings. We're not sure where they waddled in from but need to get them moved as we have two large dogs who would love nothing more than to have duck for dinner. We've already called animal control, but they appear closed for the day now.

Any suggestions for getting these guys moved to a more appropriate area?
