Gryffin LOVES foraging toys. I have him on a rotation- right now he has pretty easy foraging toys (he too has the 4 drawer set), and I also put a "tiki takeout" in there, but he hasn't figured it out yet. I'm starting a rotation of all my birds(most specifically the Timneh, 'Too and HH) with foraging toys. They haven't been able to destroy the acrylic ones, and I like to change it up, and keep it interesting. My too is a master at the treasure chest. Gryffin is just figuring out what Foraging toys are all about.
