I am not quite sure why longevity is important? I keep a flock, I add birds and remove birds from my flock. Sure I have my favorites,. But animals do die, everything does. I fail to see the advantage of keeping hens alive for a long period of time. I would rather have an active, healthy bunch of birds, than old stiff and in pain birds.
I like getting eggs, a flock of birds laying once a week, is not what I want. If they are active and healthy and doing fine, I would not cull an older bird, but I do expect them to die, and am not in unbearable grief if they do so. Things do have a life span. Give them the best life you can, and move on.
I love getting new chicks, and it is the circle of life.
