I’ve looked at the same pictures you’ve looked at and the garden is perfectly nice and neat. The veggies are in raised beds which always make things much nicer and neater. If her neighbors and the city council were smart, they’d befriend her and maybe get a nice fresh tomato or ear of corn.
I hate to tell you but there is a strong movement to bring back chickens to the suburbs. Not roosters but hens. For the fresh eggs of course. I recently took a course on raising hens for the backyard but rejected it. A hell of a lot of work and you must - obviously - devote a lot of time to it.
We raised chickens...once. Cleaning the coop is about the worst job I can imagine for a hot, humid summer day. I am an avid tomato gardener. My friend with *free range chickens* cannot keep any sort of plant alive because her chickens eat everything, right down to the ground. She cannot bear the idea of penning them. So: my tomatoes for her eggs and everyone is happy.
Also, my chicken-raising experiment took place back in the 1970s. I can’t remember the exact accounting, but I believe it cost me about 10x the supermarket price to raise my own chickens and back then, cracked corn was cheap. Of course, so was chicken.
