i've had ducks that were nice slug eaters but then i got muscovies and the ate the garden not he slugs and bugs. would like to go back to animals helping me garden. my chickens are nice but don't eat slugs. do you have, know if guineas will eat slugs? or which breed of duck was it that was gentle on the garden? i remember the ducks as light brown, and not tall and skinny like a runner. thanks.
