I have a boring desk job, but I would much rather be a self-sufficient farmer. BUT I'm not physically fit for that kind of life, and would never make enough to survive, so the best I can do is have some backyardchickens and LARP as a farmer in my free time.
Similarly, I believe most chicken breeds would prefer the jungle environment of their ancestors, even if they are no longer physically fit for that kind of life. So the best we can do is try to make them *feel* like they have that kind of environment. With, say, a spacious run, places to roost, maybe some plants and insects.
Is it possible to approximate a jungle-type environment, even with severe limitations? With, say, houseplants, a sandbox, other enrichment activities? I think it's worth trying. My own chickens free-range in the woods, but I try to be open-minded about other ways of doing things.
