Hi Gilda, turkeys will eat every green thing in sight, as well as the insect population, mine (3, 1 hatched in incubator and very tame) eat all of my hostas, berries,and ornamentals that they can grab. My chickens scratch too much, geese are complete vegetarians and will not even look at a grasshopper, however, my beautiful khaki campbell ducks are insect vaccums! Their entire day is composed of looking for any kind of insect, large or small, and eating it. They dont scratch, they are so respectful of my plants, also, they dont eat them. Ducks are the way to go.
