Yeah, that's going to stop a lot of people from getting chickens. This all actually goes back to post-WWII and the creation of the suburbs. The suburbs were the anti-thesis of the farm, and nothing is more symbolic of farm life than chickens. Many soldiers during WWII were "farm boys", who decided after the war that they weren't going back to the farm. There was the GI Bill to help get an education and suburban neighborhoods going up everywhere. Instead of planting crops, all that time and energy got devoted to planting grass and having perfect lawns. Chickens were not welcomed. Easter ducklings were, but then they would soon be dumped in ponds at parks.
That way they can tell you what they want to tell you, and later deny they ever told you what they told you.
