How old is she? Is she spayed?
First, take all of the wood chips out of her cage. Bedding isn’t necessary for bunnies, and in fact, it can completely prevent litter training with many bunnies. In addition, if you’re using pine or cedar shavings or if the litter is scented, it could be very bad for her health. You might want to move a rectangular or square litter box into the cage; most bunnies don’t care for corner boxes.
Next, try putting some poops and a few pee-soaked rags in her main litter box. Pick up every “stray poop” and immediately throw it out or put it in the litter box. This method made my rabbits get near-perfect litter habits in about a week. Bunnies have a very good sense of smell, and they’ll know to poop in places that smell like old poop and pee.
If you’re still having trouble, you can try putting some tasty treats (fruit, oats, mint, etc.) in the litter box right after you feed her to make her sit in there. They tend to poop right after they eat. Also, if you catch her “in the act” of pooping/peeing outside of the box, you can quickly lift her up and put her in there. Also, I recommend only having one litter box until she starts using the one in her cage.
