I am still weighing getting a cockatiel, but I have been reading what determined chewers they are. I would only allow free flight in my bird room, but it had loads of cords since I have hanging lights with UV bulbs and fluorescent/LED lights on top of cages. (See photos.) I think putting tubing around all of that would be impractical and not wholly functional.
How likely is it that a cockatiel will chew on electrical cords?
