Funnily enough I have ordered some geese hoping that they will eat the nettles at one end of my field... Save me a job with the strimmer and I daren't use weed-killer on them just incase one of the dogs, ducks, cats or chickens happen to want to go to that end of the field, and you know they will, the minute you don't want them somewhere, that's the only place they want to be!
