My hens are getting to the point they aren't laying anymore. Because I love them, as pets, I can't kill or eat them. For me it would be like eating the family cat or dog. But in the context, I can't have an animal sanctuary in my suburban backyard. So, I am donating my spent layers to a friend who will humanely kill and process them. Doing that may be a better option for you. They way I look at it, Chickens, like other domestic livestock, doesn't live very long. Its not bred to do that. They will die relatively young and there's nothing I can do about that. Knowing that, I prefer my spent hens be eaten and feed a family rather than suffering in pain before rotting in the ground. It's a tough choice, but it must be made with a clear mind and even clearer ethics.
