I think the first thing to understand is chewing is a natural behavior for a bunny. Bunnies chew. This is inherent behavior. Chewing is also important for their teeth as it will wear it down. However, the issue is, what does she chew? Chewing something will be appropriate, and chewing others can be dangerous and also inappropriate (by society’s and our standards).
it seems like you have lots of things for him to chew instead, but as I can confirm, that doesn’t mean that your bun will chew them. You might want to look into preventing the bunny from chewing things that can be blocked off or prevented.
For the hutch, is is possible that your bun is bored? is there a different or larger set up that is possible?
Also getting neutered and spayed can be a large help.
Finally, is there anything wrong with chewing the hutch? I assume it is made of wood. If chewing the hutch won’t cause safety issues and won’t destroy the functionality of the hutch, is it that bad that she chews on it? This is really just a question so I can better understand.
