Hi, we live in the city, so we can't let our chickens wander about freely. This means that in the winter they are generally confined to their coop and small run, since we can't move their tractor around the yard in the winter. They are doing well and all, but I feel sorry for them sometimes, because it must be boring being in that little enclosure all day. Are there like activities or games you can play with chickens to give them some attention and exercise? Or am I being silly?
