Sorry Tigger, not enough info for helpful advice here ...
a few questions need answers here ...
1) You have a 15 yr old B&G who HAD a companion her whole life ... well, why not now? Did you take her in as a rehome? Did you rehome the amazon? What's the story there?
2) How was your B&G around the other birds? Aggressive, territorial, and just how jealous is she?
3) What is YOUR experience level with large birds? All larger birds, I feel, take very experienced handlers/owners to train correctly ...
if you could answer these questions, and others that may arise, we will have a better chance of answering you with some decent advice ...
