Drill or cut a 'feeding' hole near the bottom, small enough that your bird's head can't get stuck in it. Next poke or drill a hanging hole in the lid. Lastly fill it with hay or paper shred plus seeds and treats throughout!
Cheap, easy DIY toys for small pets. Just use the toilet paper and paper towel rolls you're already throwing out to make affordable toys for chinchillas, rabbits, guinea pigs, rats and other small pets.
