Hello and welcome to Binky Bunny. Pellets should be fed according to a rabbit’s weight. Do you know how much your bunny weighs? Feeding charts will differ, but the one that was made up by the vet for the sanctuary where I volunteer states that 3/4 cup of pellets per day would be for a rabbit weighing 11 – 15 pounds. If your bunny is in that range, then she is getting the right amount. Some people do feed their rabbits less than the recommended amount, though, if there is a tendency to gain too much weight or have messy droppings.
Timothy hay is fine. Your rabbit may also enjoy any of the other grass hays, such as orchard grass, meadow grass or oat hay.
Regarding veggies, the recommended amount is 2 cups per day for a 6 pound bunny, so again, it’s helpful to know your rabbit’s weight. Some people (like me) don’t actually measure the veggies and may give more than that. It’s good to have a variety of greens and veggies, and some are better than others so they can be given more frequently. If you click on the BUNNY INFO at the top of the page, it has a lot of good info on all the basics of rabbit care, including feeding, with links to articles on good veggies.
Wood stove pellets are fine to use. Just make sure that they contain no accellerants. Horse stall pellets also come in large bags and are very economical. You could find those in feed stores or Tractor Supply stores.
I’ve had both male and female rabbits and I don’t think I’ve ever done anything differently with their care.
