At 6 weeks, buns are as a rule weaned. They’re often taken from the mother at that age, but are kept together with their siblings for another 2 weeks. She should be fine with you, but she is of course very young and vulnerable. She might be better off with you than if she were to go back to the breeder.

It’s a bit strange that she hasn’t been eating pellets. I assume she has been filling up on less suitable food. Since rapid dietary changes have the potential to cause serious stomach upset, I’d say keep giving her what shes used to getting, but mix it up with pellets and hay in a gradually increasing ratio. In my opinion orange peel is a weird thing to feed buns, esp baby buns, but since it’s what the mum has been eating, the babies have been eating it too via her milk. This is how it is believed that rabbits learn what plants are good to eat, via molecules from those plants in the mother’s milk.

Get her a good quality junior pellet to mix with the other stuff she’s eating. You can give alfalfa hay or a mix of alfalfa and grass hay. Alfalfa has extra protein and calcium that a growing bun needs. Hay is, as you know, the most important food for an adult bun, so you want to lay down good hay-eating habits as early as possible.

Weekly weighing is very good for keeping track of things. She should gain weight rapidly at this age. You can weigh her in a bowl on kitchen scales. It’s good to keep a little diary of her weight and what food she eats etc.

Hey!

I don’t own any rabbits but have done tons of research. I hope that you can eventually get her (I’m assuming the bun is a doe?) off that table scrap diet. I haven’t tried these pellets (obviously can’t if I don’t own a bun) but they are generally trusted.: “Oxbow Rabbit Young”.  Once she is older you can also switch to Oxbow’s Adult Rabbit Timothy Hay Based diet. 🙂 Best of luck!
