Most definitely hold off on getting Tiki a birdy bud right now. Before getting another, you have to take time to form a very strong bond with Tiki. If you do...then if you decide to get another he will still be attached to you.
Besides if hubby is home during the day he can talk to Tiki and keep him company too right? He will see your whole family as flockmates eventually...that is a good thing
As for toys, it's not a good idea to give them mirrors until they are bonded with you either, or they can form a bond to the birdy in the mirror.
Music or tv on when no one is home is always recommended. They don't like silence. In the wild, silence is a sign that a predator is in the midst.
Oh, and one more thing in case you didn't already know-leaving a nite lite on is also good. Helps keep the might frights away and helps them to see IF they do get frightened during the night so they don't bump in to things in their cage.
