I've been waiting to do something like this for my birds since summer. They LOVE this branch (and I've got more I can clean up for them!). http://resirem.com/pov/main.php?g2_view=core.ShowItem&g2_itemId=1510
Excuse the mess, we've been busy/sick and haven't had energy to clean. I had just given them millet today, and cleaned up after that. This is between my desk and my roomie's desk, it should give you a good idea of the set up. I even have a wooden swing they usually ignore, an egg biscuit tied to one spot, a bird necklace toy wrapped around one part (though I may move it to a different place) and that ball toy thing.
They haven't left this thing all day, and I spend most of my time here. They've behaved all day. If they keep this up and stop with the constant screetching, I may just keep the little jerks LOL
