Do the jurisdictions that outlaw keeping poultry (or other livestock, for that matter) have reasons that have nothing to do with health and welfare in mind? Think about it. If you raise your own that means fewer trips to the grocery store, hence less profits and less taxes. Horror of horrors if you should sell your excess produce. I'm not a conspiracy guy, but... Think about it. There's a reason that large corporations donate to political campaigns. What do you think?
