Sandy perches are not good for parrots' feet! As a matter of fact, sand or sandpaper covered perches can actually produce sores on parrot's feet Answer Parakeets love to chew, especially wood. They will do this to sharpen their beaks or out of boredom.
Try placing wooden toys around the cage. Also, try small "foot" toys - loose wooden toys that you place on the bottom of the cage that they can pick up and throw or carry around. If the problem persists try replacing the wooden perches with sand covered hard wood perches.("Sandy Perches") These are also good for the feet, beak, and claws.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest.
