Just a little side note about donkeys..from what I've been told by the breeder I got mine from. Donkeys play reallllly rough. They bite at each others necks and jump on each other. Even if they aren't being aggressive they can kill a smaller animal. I've heard stories from people who put a donkey with their goat herds where the donkeys killed them all. I know mine hate my cat and will go after her in an instant, but to someone who didn't know them, they'd probably think my 2 donks try to kill each other all the time lol. I call it donkey wrestling. They are sooo rough! What happened with Susanne's definately sounds like a deliberate attack though.
