Try some different toys too. See what he likes. Some love destroying wood, plastic. Swings can be fun. Any toys with bells on just check the bell knocker isnt flimsy. I snap them out coz my Parrot would just break it out and swallow it. Foraging toys are a must also. They like to work for food and it replicates what they do in the wild so its good enrichment and mental stimulation and keeps them busy.
You can make DIY toys too. Its way cheaper. I know there is info on the forum and online.
Variety in perches is good for strengthening feet too. You could get rope perches, wooden perches, different widths ect, all good for feet. A cement perch or sand perch is great too, it helps keep nails and beaks trimmed. I put mine near his food bowl so he has to go on it every day x
