Every so often, you need to do bigger chores, like go buy fees or fix something in your setup. A couple times a year you need to do a deep clean of the coop (throw out all the straw, scrape any poo that's collected on the floor or wherever, put in clean straw). Sometimes a chicken dies, and that's not fun, but it is something you have dispose of properly.
Ultimately, though, it's a hobby. It should be fun or relaxing most of the time or else it's not worth it. Like gardening or running a home server. If you're trying to just save money, maybe you can save a tiny bit in this particular moment, but there are surely better ways to save a few bucks.
I ask because I used to have a good sized garden at my old house, growing enough veggies to both preserve and distribute to neighbors because I grossly underestimated the yield. While it was nice to have the neighbors love me, it was also a lot more work than I had bargained for (especially when otherwise working 40+ hours per week) and it got me thinking about community gardens and whatnot, why those might make more sense these days
Great, the guy who "cleans" the coop when it's his turn by gently sweeping it for two minutes just swiped all of the eggs again.
I always thought it was silly that everyone in the suburbs owns their own lawn mower, edger, and weed whacker. Why not have a communal shed on every cul-de-sac? ...Until I lended tools out to people and saw how they treated them.
I'd think most of the time you'd need some sort of oversight structure just to manage people.
Since you mentioned the suburbs specifically, I'll also note that, at least imo, that: - the suburbs are designed in such a way as to encourage atomized, isolated living (houses are relatively far a part, you usually need a car to get anywhere, fenced-in yards are the norm, etc). - presumably people are moving out to the suburbs because they find that lifestyle appealing, so there's some self-selection happening such that people in the suburbs are less interested in sharing stuff communally.
So if you were just trying to get 20 households that happen to live closest to you involved, it probably is too big a committment for them.
