Great ideas Wingy, it is springtime and they do get hormones and act up....my 3 sure have been! A friend once said, isnt it worth all the destructin for the love you receive back from them? Wood and things can be replaced, but the love and beautiful memories they gve us can't ever be replaced. Looking back, what would you cherish, a destroyed house and things, or memories of a sweet bird named Kiki who doesn't understand that she is doing wrong, as she can't see thru human eyes....it's her nature to seek and destroy, you can't take that instinct away from her. You can try and channel it in other ways.
When my Rikki had me in tears for her destruction, it seemed the more angry, sad and upset I got, the more she did it. I had to finally realize I had to calm down and relax and not make such a fuss, she saw that after a while and then she too calmed down. I used a lot of boxes for her to destroy, I put them on top of my kitchen cabinets and that kept her distracted from other things. Phone books in her cage also helped.
Oh, and baskets are a huge hit with Nilah my amazon....
