I got a popcorn ball to put in the chickens coop today to keep them busy since it's suppose to be overcast all day and I know they won't come out much but I'm at a loss as to how to hang it for them. Best I have came up with is pushing a hole through the popcorn ball and attatching a rubberband to it to hang it up, but will they eat the rubberband? And if not that what do I do?
