I live in Sacramento CA and I'm excited that the laws against chickens in the city may soon be lifted. The rules will allow only 3 hens. My question is this. From what I've read hens don't continue to lay throughout their lives. So what do I do when the hens get too old to lay. Even if I am willing to have an "old age" home for chickens until they die a natural death; I can't get any new chicks since I'm limited to only 3. What have others done?
