You really think chickens don’t eat bugs at every opportunity?
City folk have never seen what chickens will do if turned into a cow patch with fresh cow paddies on the ground. They will absolutely destroy those paddies digging for maggots and the flys in/on them. Followed up by hogs that will eat every scrap of the cow paddie with a vengeance. Animals only see protein and carbs they could care less if it’s another animal’s waste.
