changing cages and territorial behaviour

[daffee]

I am wanting to upgrade our robos to a bigger cage. They are currently living in a savic rody and are quite happy with that. But I would like them to have a bit more scurrying space and have been looking at the zoozone mediums and even the large as possible replacements.

My OH is not convinced about moving them and before I commit to a large and expensive cage I want to check whether it might upset the territorial balance in the cage. They are both sisters and get on fine but have had a couple of scurmishes in the past.

What I don't want to do is move them into a much larger cage and have that instigate territorialness and fighting. Does anyone have any experience of moving adult robos or other dwarf groups into new cages that can advise me? I would imagine keeping the same cage accessories at first would help? What do you all think?
