Barrel of Fun Blue. Barrel of Fun is part of our new foraging line of bird toys. In nature, birds spend hours foraging for food. It's a healthy and native part of an exotic bird's life. Now, instead of handing your bird fruit and treats, you can hide them in this Barrel of Fun! Your bird will be occupied for hours trying to solve the puzzle to reveal the hidden treat. Hang several around your bird's environment and watch instinct take over.
