I'll be going away for a week in a couple of months and I've hired a professional sitter for my 9 birds; a macaw, 2 cockatoos, an amazon, 4 conures, and a budgie. She will be coming over 2 times a day for about an hr. each time. She's been over a couple of times and my babies adore her. They are extremely spoiled because I work midnights and spend all my days with them. Do you think I have anything to worry about?
