My son (age 30) is interested in getting some ducks for here at our farm. we have a nice creek that flows by the house and we have wild mallards go by frequently. My question is --will they come to the house and get into my flower beds and wreak havoc--I just put my chickens in a run this yearbecause of this and they no longer free range--we would like the ducks to be free to go to the creek and back to land without caging them up during the day. but, if they are gonna be a nuisance at the house I need to know. Thanks
