Our pet quail, Chalupa, loves toys! Anything she can walk under or peck at. I've been getting very creative and crafty with my toy ideas for her. I got cheap mops from the dollar store, took off the stick, drilled a small hole in the plastic part and attached a paperclip so I can hang it in her home. A few of those in there and she LOVES to get cozy underneath them. Anywhere we can put small wash cloths (aka "blankets"), she'll get cozy on those.
I have also found inexpensive bird toys that hang long with bells on the ends, she likes to peck at those. Anything that's shiny or with lettering she'll peck constantly! I found some pom poms that are shiny.
Mirrors are also fascinating to her. She could stare at herself forever. Hahaha I got a "fun house mirror" that I set on the ground. That's been her new favorite thing.
And of course anything else that she can hide in or near are good when she wants to nap. Our local bird shop actually have bird tents! Yes, it's silly, but that's the whole point! Put a blanket in there and she'll be content until she needs to stretch out her legs and eat!
Tents sound so cute! I'd be wary of mirrors, though—I've heard some birds can become territorial around their reflection because they can't recognize themselves.
I've stopped trying to give mine toys. They just aren't that interested. Instead, I find them spending time "foraging," dust-bathing, and napping in covered areas. But I can see toys being super important to birds kept in tighter spaces—any enriching helps!
