Is it a standard donkey or a mini? All donkeys have good guardian instincts but a single mini would not be able to fight off a pack of dogs or coyotes.
As far as her being skittish . . . all donkeys are naturally distrusting - that's part of what makes them such good guardians. I've been told that if a horse trusts you it will do anything you ask, but a donkey will only do it if wants to. If she has been raised around people and handled, you should be able to handle her after she learns that you won't hurt her. If she has not been trained, however, and you are new to donkeys, you could have a real time trying to handle her for things like shots, hoof trims. I agree that you should see her before you buy her, and ask the owners to show that they can pick up her feet, halter her, and touch her all over. If she has not been trained to do these things, I would not get her.
I have heard of donkeys killing goats. I think Jenny's are less likely to do this than Jacks, but I honestly don't know because I've never seen one attack a goat. I would not keep an intact Jack in with female livestock. I've seen Jenny's and geldings chase their livestock to make sure they will listen . . . which is okay because they need the herd to do what they want in a time of danger. Usually you will see them chase the livestock to the barn or shelter.
Do you know anyone who has horses or donkeys? If you can, I would try to take someone who knows about equines with you who might be able to point out any problems. $80 is pretty cheap for a trained animal.
