Here's where @Kiki and I disagree; here we have roosters, hens laying eggs, hens not in lay, for whatever reason, and often chicks. Everyone gets an all-flock feed, 20% protein, with grit and oyster shell in separate containers.
If we had an all- in, all- out commercial type flock management plan, with layers in confinement eating nothing else, we'd feed a layer feed and nothing else. that's what it's for, not so much for mixed flocks of larger birds who also eat other stuff.
And if most chickens weren't bred from one year old parents, and so not selected for longevity, our pet chickens would have a better chance to have longer lives.
