Lol I never thought you could teach a rabbit tricks, but that sounds cool!

Rabbits aren’t really like dogs, and probably the only way you could teach them a trick is with a treat, and if she’s treat aggressive there’s nothing you really can do.
I just let my rabbits eat in peace.

Oscar used to be insanely food aggressive. I would get attacked every time I fed him anything. I tried a few different things, but most of it made him worse. Then I tried this: I would put some food in my hand, make a fist and place my hand on the floor. Oscar would come up and start going nuts as soon as he smelled the food. At first he would of course act aggressively, bite my hand and dig at it. If he did any of that, I would remove my hand and say “No”. After a couple of seconds, I would try again. He learned that the food went away anytime he displayed aggression and after a while he became calmer. If he managed to be around the food for a few seconds without attacking, I would open my hand and let him eat. I repeated that process endlessly, slowly increasing the time he had to stay calm before I gave him the food.

He’s much better now, he still goes nuts when food is involved, but he doesn’t attack us anymore. Unfortunately, you will most likely get bitten during this process, maybe a glove would be helpful. I didn’t use one, but it’s something to consider. Also, I would make sure your bunny has already eaten before doing a training session, if she’s not hungry she should stay calmer.

Good luck!
