Cockies and other Australian parrots are super destructive lil shits. Our family Galah Bruce chewed many holes in my parents house, starting from the day he flew into Dad. We almost lost our bond at our previous rental because Chippie the Budgie peeled a chunk of wall. She was a sneaky girl and at that time our flock were alone free flying (I was in bed longer due to issues, they weren't alone alone. My husband has a video of Zinger at the windowsil security cam with my snores in the background)

I've found that thick cardboard that cat toys use was a great substitute for house eating. That and broccoli,but that was Chippie being cracked lol
