This extremely durable bird toy was created for just the big guys! If you have a bird that chews rope, or destroys smaller wood, then this is the bird toy for you! It has four large chains filled with over 40 large chunky pieces! Some are hardwood, some are pine, along with a few other natural items. Each chain has a solid welded, bird safe O ring at the bottom for safety. And to top it off is a cool place for treats for the birds that love to forage for their food! It measures approximately 22" long by 12" wide, and is very heavy!
