Unlike #chickens, #ducks (of the domesticated sort) can be easily herded. So Iβm thinking a robotic 4WD (or 6WD) electric truck (RC size) could patrol the yard & recognize the ducks & keep them in the yard.
Sure, a #BorderCollie could do it too, but then I gotta deal with dog shit, & the duck shit would be plenty of shit for fertilizing the yard.
