Anyone here use a donkey as a guardian animal? We have goats in the pen, and coyotes out, and need to keep it that way. The choices for guardians seem to be a guardian dog or a donkey. The wife says donkey, but how do you know if one will do a good job. Is it simply luck? The man across the road has one with his cows, and that thing makes a ton of noise. Others are never heard. I just hate to spend money on one to get it home and find out it is just a pet. Any thoughts?
