I make braided balls for my budgies. (They aren't big on shredding.) I use corn husks (tamale wraps) or paper.I'd like to start this to show the different foraging toys ideas I've had for small beaks. I've often been frustrated by the lack of puzzle foraging toys for smaller parrots, so I've often made my own or adapted ones for bigger beaks.
This is the Caitec Cage Mounted Buffet Ball. It's meant for larger birds, but I've adapted it but put straws in the holes and layering the food on top of or around the straws.
I sometimes put a Nutriberry or a "millet ball" inside so they find a treat. I add them to the foraging box or to the veggie skewers.
