My Peach-faced Lovebird "Barnabas" loves the toy Dr. Foster & Smith sells "Paper Shredder". It comes in both large and small. They sell it also when you need extra rolls of paper.
Barnabas always calls ("Jungle Toy") when he wants me to check the paper.
The "Jungle Toy" is a fun toy for all birds. Soon one of mine will hit the button. It's bed time. They just did "hello".
Getting back to the Paper Shredder, your bird will love that, even our parakeets love it and other 2 Lovebirds.
As for feed, create your own food: boil eggs, microwave vegetables, shred bread, etc to add to their food.
After 24 hours, when you give them their next day supply, throw away any of the food you created away.
I just boiled eggs for my birds and they ate all the vegetables I made that was added to their seed.
