Chicken Swing! It's a great cheep<-(haha) way to keep birds from boredom! We put one up in each of our two coops after a tree fell down. We used some of the limbs and some rope to make a chicken swing. They really seem to like it. Sometimes, my bantam cochin Jill will sit up in it and go to sleep!
Take some old bangles you have and buy some thin colorful string from any craft store (don't worry it's cheep) then add a for of glue at one end of the bangle and then rap the string all the way around (time consuming but worth it) then glue it on the other end and add cute charms for adorable colorful DIY bangles!!
