Because it was relevant to the discussion, here are pictures of the damage my wood-chippers can do in a day..
Zuri's mess
Joey's mess
Now the wood toy they destroyed wasn't particularly big and made of pretty soft wood. But still, they now have something slightly bigger and harder to chomp on and there are still plenty of wood chips in the bottom of their cages. Not that I'm complaining, the mess is pretty much localized in their cages and it proves that they were busy doing something.

Forgot to answer that earlier, 4 out of 5 birds are flighted. Petey is kept clip so that she can't go after my other birds and possibly attack them. Until I can trust her enough that she will not do that, she will be clipped.
