Chickens are active foragers that spend their time scratching up roosts and seeds, snipping greens from nature’s salad bar and going bonkers for bugs. They know what they need and want to eat.
Nature didn’t design chickens to eat only processed pellets. Just like we wouldn’t eat cereal 365 days a year! While grain should be an available free-choice, birds of any type need access to tasty fruit, grasses and insects.
