Our thinking is that we are home nearly all day everyday (run errands only once or twice a week, and I run the kids to high school each day). We have a 5-1/2' manzanita tree/perch that we plan to have the CAG on as much as she/he wants. Plus lots of holding, of course. :-)
We have a table perch to put next to my wife's chair. She is recovering from a stroke, but has use of her right hand, and can stroke, hold, and cuddle with (soon to be) our CAG.
For about 4 years we cared for my father-in-law's B&G Macaw, she was only in her cage when we weren't going to be in visual contact, not at home and at night. She spent most of her time on the play perch and I handled her as much as I could (I was working then). My F-I-L bought her from customs quarantine and I was the only one that would deal with the beak and what was eventually occasional biting.
We are looking for another cage because we bought a hardly used (plastic wrap still on the play top tray) very nice quality P/T quarter round corner cage (30" radius), but our breeder said it was too small, we will probably use it as a night cage in our bedroom for max dark time.
