I lived in London and had chickens for years. Just no rooster. Bylaws said no.
For me it was becoming self sustainable. Being less dependant on the systems. Taking that leap of faith. No one complained.
4 weeks before i left, someone reported me, so it was then that i placed my chickens. They gave me a warning. Had i stayed there, I would have approached the city in a peaceful, spiritual way.
Moving through the paralyzing fear. The fear they feed off of.
