Typically young adolescent bunnies may pee everywhere. Have you considered having her spayed? She's about the age that some vets do it. (Here it's 6 months). I strongly reccommend having it done bc it should double her lifespan and improve her behaviors - particularly in the litter box department!
Acacia was litter trained a little bit before she was done but since she has been perfect EXCEPT when there were threats around. Before she got used to my dog/cats when I moved back home she would pee along the perimeter of her enclosure. Also, during separate free runs, both my female bunnies (un-bonded) would pee along the baby gate to establish their territory and dominance. So is there any threats from other animals that could be encouraging her to feel threatened?
Also, The cage litter (I assume you have a cage, if not whatever you're covering the bottom with) needs to be different than the box litter. Some people use kiln dried or aspen shaving s in their commercial cages but also in the litter box, this means she doesn't differentiate the two- regardless of the hay and litter box. My bunny has plain sheets of newspaper in her box to pee on while the bottom of her pen is carpet and all the levels are only lined with newspaper but topped with blankets.
But, you're doing good with the hay feeding in the litter box!!
Hope this helps!
