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!
pinner: This is a very good paper mache clay. It holds lots of details and is very strong when dry. I've used this clay in silicone molds and dried them in a microwave using 2 minutes intervals. I can complete small 3 inch pieces in about 10 minutes.
