I have tried with the feed bucket. She runs like hell. watches me from the woods coverage for me to leave then comes for the feed.
About a year ago I called the owner to let him know his Mule was at my farm gate: He came and was pissed off at me and the Mule. I offered to walk the Mule back to his farm(3miles). He refused. He actually got in his truck and tried to run the mule down.

I did call the police, to report him for cruelty.
Needless to say the Mule is terrified of humans at this point. I am trying to win her over to catch her, pen her, and with any luck fine her a home.
Sheh does have a nasty kicking end.
