Hi there - I'm looking for citable information on flock size for happiest hens. My city only allows 3 birds, which I think is ridiculously small. It's also not much for providing eggs for a typical family with kids. Another city near us and similar allows 6. I'm considering going to the city council and speaking and asking them to up the number. The idea fairly terrifies me, but I'd like more chickens. Given how tightly my 3 birds stick together, I think it's important for them to be in a group, and that they'd be happier in a somewhat larger flock - but I need something I can cite and show that will be more convincing than "I, with very little experience, think so". Anything?
