Hello Paul, I worried about this last year when I wanted to keep chickens. I live in a city centre, with a small garden approx 40' x 30', and neighbours in very close proximity. I chose not to tell anyone at first, only my immediate neighbours, who were fine with it. Now thanks to the occasional rosey bout and people being in the gardens more, most people on the street know. So far everyone has been fine, mums bringing the kids round to see the hens, and sent away with half a dozen eggs works wonders. Keep them clean, which I do weekly, and take anti vermin precautions, and all should be well.
