foraging ideas

Unfortunately, money has been really tight lately. My birds shredded their current toys and I ran out of toys to rotate thru. I’m in need for diy toy ideas that I can make using things you’d find in a house. I crochet so I have a ton of yarn and buttons. Anyone know what i can make with that...

Hi! I got my finches almost a month ago, and I was wondering if you guys know of any foraging toys (can be store bought or diy) that are small enough for finches tiny beaks. So far the only foraging activity I’ve gotten them to do is pull millet sprays out of a sea grass mat. Thank you!
