I saw this today when I got online. It really saddens me. The oldest hens of my flock are still living minus one who became egg bound. I'm sure a few of them are only laying a few times a week or less, but I told my husband that our first flock gets to live until they die naturally of old age. Some of the younger ones will be chicken dinner when they stop laying, but I think it is healthy for the flock to have a few "seasoned" members to show them the ropes. Especially since I now allow my flock to free range without my complete supervision. I finally started trusting my rooster to do his job, and so far he hasn't failed me. I don't know what I will do if I loose him, because he's my favorite and I think he is the best rooster ever.
Even though I am starting to look at my chickens as part of the farm/ranch, I still see certain ones as pets. Beakman and the older hens especially.
