new Cockatoo

Question
1st came the 2Conures, followed by my umbrella "too", Nani.  I just bought a rose breasted too, baby, about 16 weeks old.  Obviously my umbrella isn't thrilled.  These birds will not be housed together, but eventually I'd like them to share the hanging manzanita tree we have indoors.  Any suggestions how to bring them together successfully?  Thanks!  P.S.  Umbrella walks wide circles around conures and has never gone after them, but having a real hissy fit over "Rosie"

Answer
Hello Cheryl and thank you for your post.
Nani does not object as much to the conures only because they were there first.  Any new bird that you bring in, Nani will object to.  
Make sure that they are introduced slowly and in separate cages.  I do not recommend letting them all out together.  It is possible for Nani to attack any and all of he other birds which could prove to be fatal as Nani is so much bigger than the conures.

I hope this helps.

Good luck and God Bless.
