US here, I grew up in a township, part rural part suburban, on a farm and this was not a concern for most people out there but all my friends and their families from the suburban side were squeamish. I think it comes down to repeated misinformation reinforcing a fear.
What I’m trying to say is that I think those people I grew up with maybe had a misconception that the risk was much higher than it actually was. We maybe should normalize pet chickens for small properties. Daily fresh eggs are so good and chickens are adorably goofy animals.
