First of all, my condolences. My family has a terrible history with cancer, and I can most certainly sympathize.
When it comes to bonding, it really depends on the bird. It only took my girl, Monty, a month to take a shine to me after I brought her home, while with others it can take a great deal of time. Bottom-line, most birds are able to re-bond.
These guys are highly adaptable, so I wouldn't worry too much about the outdoor/indoor thing, cruel as that might seem. The question is: are YOU comfortable homing the 'too?
After a brief Google search, there are a number of rescues not too far away from you, though I can't vouch for their credibility. It's really too bad that we aren't closer; I'd be more than willing to house a 'too in need.
