I think that all sounds like you’ve done your research keep them completely separate until 2 months post spay (girls take longer to adjust to the hormones and can be extra cranky). I’d let her have her own room while she settles in and gets used to everything, then you can permanently keep their cages at least 6 inches apart. After you’ve moved her into his room, you can start prebonding and switching all their stuff around. You prebonding all the way through bonding, so it never really stops until they are fully bonded. You may be keeping them separated longer than 4 months, as most vets will not spay a female before 6 months old.

I’ve been living with separate boys for almost a year. The biggest hassle is honestly the poops that are everywhere. They’re both litter trained, but they aren’t bonded yet, so they naturally have territory wars via poop. This will most likely happen to you as well, when you start letting her out in the same space as him. Aside from that, it’s making sure they both get equal amounts of play time. Just in general, its twice the work because it’s another separate bun. So however much time it takes you to do anything for your single, double that when you add your girl.

I have to ask, why a 6 weeks old? That’s barely weaned from it’s mother and could stress her out unnecessarily. Bunnies really shouldn’t be going home until they’re 8 weeks old (2 months).

Good luck and I hope this helped

ohhh I got it
Owning a bunny in general is a learning process hahaha. we’re always learning something new. I think it sounds like you’re all set to welcome your new little love in
