Sometimes it's her wanting attention...but sometimes she actually is basically running up at me and squeezing between my horse and I to push me away from him :( she was actually threatening to kick me yesterday when I was trying to take my horse out and she wasn't pleased about it.
After I put my horse back in I tried to make friends and gave her some soaked alfalfa cubes that my horse didn't finish. I don't want her to hate me but I don't want her to try and keep me from my horse. She kinda follows me pinning her ears when I'm walking him and trying to keep her back. Few times she's tried to grab at me :( Posted via Mobile Device
Don't try to bribe her with alfalfa - food bribes don't really work with donks, and alfalfa is NOT good for them.
I say stick to the one to one ground work. Groom - hug. Then some really tiny training. Halter and then walk on command - or back up - something small. Training is NOT like a horse, you need to exercise tons of patience.
I think, reflecting on what you have just added, that I would go for the back up command. It will serve you well in the field, and will help your communication with her.
It's also good to remember that while a horse's instinct is to run for it when there is perceived danger, the donkey's is to stay put and use its wits. They like to stand and think a lot during training as well, and this has given donkeys the reputation of being "stubborn." When a donkey is just standing, it's not necessarily refusing, just considering the situation - that's what donkeys do. Patience is the key, like SR says. Lots of praise and positive reinforcement for learning and following instructions and displaying desired behaviour on request. Once they have learnt something and they think you're OK, they will respond really quickly to your requests. It won't always take ages, that's just at the start!
You can use your own physical presence to back a donkey off you if it really is displaying aggressive behaviour, like nipping or kicking. You have to be unafraid and make eye contact and show you mean business. Stomping your foot at a donkey reinforces this, or kicking at the air, or slapping its backside with the flat of your hand with a nice bang, and obviously verbal reprimands. But like SR says, make a positive relationship with the donkey first, away from the problem behaviours; then this will be far more effective.
It's not your donkey, but hey, donkeys are good fun!
