I feed no veggies to my rabbits, but this is what I give my Holland Lops. They get 1/2 cup of Kent top show professional pellets a day, they get unlimited amounts of Kaytee orginal(plain) Timothy(despite rumors the hay isn't bad, however other products produced by them aren't good for rabbits, like food with seeds and colorful bits in it or hay with mango pieces, the original hay actually is a really nice quality hay) and I feed them a teaspoon of mint conditioner twice a week. (this is a treat). They also get cheerios and sometimes rolled oats as a treat. Usually I use rolled oat if they have a looser stool. With my water I put a lot of different stuff in it. I get a gallon to store the water (milk jug that has been washed out and sanitized) and I put a tablespoon of apple cider vinegar in it (slowly going up to 2 tablespoons) And I put a teaspoon of extra minerals in the water.
The extra stuff I give my rabbits isn't necessary for a pet but I give it to my rabbits to keep them in good condition and to make sure they are getting all the nutrients and minerals they need. If you aren't giving a lot of veggies you need to give more pellets because she isn't getting the nutrients she would be getting from getting a normal amount of veggies she would need a day. You also aren't giving her a lot of hay so she isn't getting all the fiber she should be getting. This is the proper percentages your feed should have>>
Protein- 14--20% ideal amount 16-18%, Fiber- 12--22%, sources say the higher the better, around 18% is ideal, Calcium- less than 1%, Fat in your feed should not exceed 3%.
I would give her 1/2 cup of pellets because she doesn't really have any other source of calories coming in. As you increase the amount of veggies decrease the amount of pellets. For veggies you feed 1 cup per every 2 pounds of body weight. I also would start giving her more hay, it's important they always have hay because it keeps there gut moving, it more important with rabbits that have longer fur(wool) or rabbits that are molting.
