I'll share some of my idea if you will share yours!
One things I enjoy doing is providing toys that will give the parrot something to whittle other than their expensive perches! I use clean blocks of wood (safe wood that is treatment/chemical free). I will drill a big hole, big so that the bird isn't injured. The large hole also makes it easier to hold on to the block. I like to provide color so I used Kool-aid to color the wood.
I will share another idea soon. Please share your ideas!
