So sorry for your losses. I have a couple of older hens. I will keep them for the rest of their lives. My situation is quite different because I have a lot of birds. I have kept these birds in the same coop and now and then move birds around for breeding purposes, so they usually get new coop mates. Luckily the other birds haven't bothered them. Both of my older females have issues so they get a little extra TLC. Good luck with whatever you decide to do.
