I've heard from several different sources that donkeys are excellent guardians against predators with sheep. Does this translate into protectors of chickens/geese/ducks? And, which predators? I have a wonderful donkey, but he's been leased out all summer to a friend and she wants to buy him. If I could bring him home and put him in with the birds to help protect them, I would not sell him. Anyone with any experience?
