I keep mine busy. (43 total and 17 of which are roosters, 7 weeks old) I put "fun" food in for them. In a pan I mix alfalfa leaves (from when we load hay into our barn) crumbles, oats, cracked corn, add water sometimes or not. They go nutty over this. Or sometimes I just put a flake of alfalfa hay in the coop for them to dig and pick at. Giving them something to do keeps them from focusing on each other. They like to hunt and scratch for their food, so I let them. I also have a bulk hopper for the crumbles so they have a choice.
