I currently have 11 Gouldians (3 adults, 3 juvies and 5 chicks in the nest).
They are currently housed in 2 separate cages (not huge, but large "pet store" type).
I'm in the process of finishing a LARGE cage for them (made from an old armoire).
In the meantime, I'm going to be acquiring a pair of RCCB

My intention is to reduce my Gouldian collection once the babies colour up and house ALL the remaining Gouldians and RCCB pair in the large armoire-cage.
I will NOT be putting in nests.
If I breed, they'll be moved to a separate cage.
SO, my questions is: (having never owned RCCB before and being about 1 yr into owning Gouldians)
Do RCCB have any different/special housing requirements than Gouldians? ie. sleeping habits, do they roost on perches etc? bathing requirements?..? food access..?
I just want to keep everyone happy!
I'd rather have the cage ready from the start instead of altering the inside after they're all in there..
Any tidbit of info is welcome regarding a Gouldian/RCCB combo!
Many thanks!
