We cull the very sick (because vets by and large don't know about chickens, and entering the vets cost about 3 times the cost of the chicken) and the roosters (because you really only need one per flock). Other than that, they have space outside to roam, and we even have some "freeloaders" - hens that have become too old to lay, but we keep them on anyway.
