Oh, this was hilarious!! On Sunday, I made a new chicken tractor (PVC hoops) for Bo and the Production Reds (my pullets). Today, I put them inside, and one of the little bungee balls I used to tie the door shut fell inside (it is a small ball with about a 6" loop of bungee cord attached to it). One of the Reds picked it up, and the chase was on! They played "Bungee Ball" for about 10 minutes, with several steals and lots of full-"coop" action. MAN, I wish I'd had a video camera!! However, I was laughing so hard, I probably wouldn't have been able to film!!
