My small bird prefers really big toys, is that normal?
Some people may think this is an unusual question, but it really is not. Bird toy preferences vary greatly among individual birds.
Some small birds such as Conures and Mini Macaws,,may prefer larger bird toys with lots of soft wood to destroy. Larger bells make more noise which seems to be a good thing for some smaller birds. Sometimes the small size bird toys just don't meet the chewing and play requirements of such active and fun loving parrots. 
On the other hand, there are also some larger birds who enjoy smaller delicate and more intricate bird toys. My amazon PJ loves small toys that he can hold in his foot and dismantle. I never give large bird toys to my African Grey Shiloh as he is convinced new toys are out to get him and smaller toys he will investigate after a while. He enjoys small and medium sized bird toys only. My Macaw Cosmo, will play with all sizes of toys from Cockatiel size to the largest macaw size toys. Sure she makes quick work out of those smaller toys, but sometimes she just needs some variety.
When giving smaller toys to larger birds, supervise, supervise, supervise. Small beads, bells, and such, are often not a good choice for large parrots and sometimes these toys need a little modification to remove tiny bells or other such parts before given to your parrot for safety. Even if you think you know your bird and how he will play with a smaller toy, it's still wise to supervise playtime and the safety with any and all bird toys.
Small bird toys can often make a great foot toy for larger parrots. Large bird toys with lots of colorful soft wood shapes can often create a great challenge for smaller birds who love to destroy and need to stay busy.
There is a perfect size bird toy for every bird. Sometimes it may seem like a mismatch when in reality it's the perfect match. Just remember to supervise your bird as you would a small toddler, as birds can always find a way to get into trouble. Check toys often for wear and tear and replace just as often for new fun and more fun.
