The previous owner fed them in the winter and allowed them into the yard. The back yard is fenced, so we could most likely keep them out. However, my husband thinks they're cute and wants them to keep coming in. I am looking for reasons NOT to have ducks in the yard. So far I have been told they are aggressive towards small children, sometimes chew on plants or other stationary objects, and leave droppings everywhere.
All advice is appreciated.
I'm afraid I would side with your husband. The droppings are the main problem - ducks are very, very messy that way. Unlike a dog mess, you can't scoop it up either. I don't know of any diseases carried by ducks that are transmissable to humans - you might check with a health department. They poop on the plant leaves and you end up with varigated plants.
