Get a pet sitter who will stay at your house and give her attention. That way she will be comfortable in her own home instead of in a strange pet store overnight, especially for that many days.
She'll be okay. But she will also be glad to see you when you come back. Don't worry about her.
Hi so I'm leaving my macaw alone for 7 days. Someone will drop by daily to change water and put food. I'm very worried about her, also put a few chew Toys knowing she will get bored. Will be she be ok?
